4. WARNINGS AND PRECAUTIONS
4. WARNINGS AND PRECAUTIONS
The patient should be warned of the potential risks of defibrillator malfunction if he is
exposed to external magnetic, electrical, or electromagnetic signals.
These potential interference sources may cause conversion to inhibited mode (because of
noise detection), erratic delivery of VT or VF therapies, nominal programming, or much more
rarely, irreversible damage to the device’s circuits.
The main sources of high magnitude disturbance are: powerful radiofrequency equipment
(radar), industrial motors and transformers, induction furnaces, resistance, arc-welding
equipment and high power loudspeakers.
Electrical Isolation:
Do not permit the patient to contact grounded equipment that could produce hazardous
leakage current. Ensuing arrhythmia induction could result in the patient’s death.
Antitheft gates:
Since antitheft devices at the entrance to stores are not subject to any safety standards, it is
advisable to spend as little time as possible in their vicinity.
Airport detection systems:
Since airport detection systems are not subject to any safety standards, it is advisable to
spend as little time as possible in their vicinity.
Work environment:
The patient's work environment may be an important source of disturbance. In that case,
specific recommendations may be required.
High voltage power transmission lines:
High voltage power transmission lines may generate enough disturbance to interfere with
defibrillator operation if approached too closely.
Communication equipment:
Communication equipment such as microwave transmitters, linear power amplifiers, or highpower amateur transmitters may generate enough disturbance to interfere with defibrillator
operation if approached too closely.
Home appliances:
Home appliances that are in good working order and properly grounded do not usually
produce enough disturbance to interfere with defibrillator operation. However, there are
reports of device interferences caused by electric hand tools or electric razors used directly
over the device implant site. Patient should also avoid using induction ovens and cookers.
CAUTION: Do not tap sharply on the ICD can after implant, because the ICD's sensing
circuits can detect this as P-waves or R-waves, and such oversensing could result in
inappropriate pacing, inhibition, or therapy. Normal activities after implant do not result in
such oversensing.

4. WARNINGS AND PRECAUTIONS
4.1.
RISKS RELATED TO MEDICAL ENVIRONMENT
It is advisable to carefully monitor defibrillator operation prior to and after any medical
treatment during which an electrical current from an external source passes through the
patient's body.
Magnetic Resonance Imaging:
MRI is strictly contraindicated in cardiac defibrillator patients.
Radiofrequency ablation:
A radiofrequency ablation procedure in a patient with a generator may cause device
malfunction or damage. RF ablation risks may be minimized by:
1. Programming Shock Therapy and ATP to OFF.
2. Avoiding direct contact between the ablation catheter and the implanted lead or generator.
3. Positioning the ground, placing it so that the current pathway does not pass through or
near the device, i.e. place the ground plate under the patient’s buttocks or legs.
4. Having external defibrillation equipment available.
Electrocautery or diathermy device:
Diathermy and electrocautery equipment should not be used. If such devices must be used:
1. Keep the current path and ground plate as far away from the device and the leads as
possible (a minimum of 15 cm [six inches]).
2. Before procedure, deactivate ATP and shock therapies.
3. During the procedure, keep the electrocautery device as far as possible from the cardiac
defibrillator. Set it at minimum intensity. Use it briefly.
4. After the procedure, check for proper implant function. The device should never be
exposed directly to the diathermy source.
External defibrillation:
PLATINIUM SonR CRT-D is protected from external defibrillation shocks.
1. Before external defibrillation, deactivate ATP and shock therapies.
2. During external defibrillation, it is advisable to avoid placing the defibrillating paddles
directly over the casing or over the leads. The defibrillating paddles should preferably be
placed in an anteroposterior position.
3. Avoid any direct contact between the defibrillation paddles and the conductive parts of the
implanted leads or casing of the implanted device.
4. After external defibrillation, check for proper device function.
Radiation therapy:
Avoid exposure to ionizing radiation. Betatrons are contraindicated. If high doses of radiation
therapy cannot be avoided, the defibrillator should be protected from direct exposure with a
protection shield. ATP and shock therapies should be disabled during exposure and proper
device function should be checked regularly afterwards. Resulting damage may not be
immediately detectable. If irradiation of tissues close to the implantation site is necessary, it
is recommended that the cardiac defibrillator be moved. As a safety measure, an external
defibrillator should be immediately available.
Lithotripsy:
Lithotripsy may permanently damage the device if it is at the focal point of the lithotripsy
beam. If lithotripsy must be used, keep the defibrillator at least 2.5 to 5 cm (1-2 inches) away
from the focal point of the lithotripsy beam.
SORIN – PLATINIUM SonR CRT-D – U463A
4. WARNINGS AND PRECAUTIONS
Diagnostic ultrasound (echography):
The defibrillator is not affected by ultrasound imaging devices.
Scales with body fat monitors and electronic muscle stimulators:
A patient with an implanted PLATINIUM SonR CRT-D should not use these devices.
4.2.
STERILIZATION, STORAGE AND HANDLING
Resterilization:
Do not resterilize and re-implant explanted ICDs.
"Use Before" Date:
A "Use Before" date is printed on the outer storage package and on the sterile package. Do
not implant the device after this date because the battery may have reduced longevity and
sterility may be affected. It should be returned to Sorin.
If Package is damaged:
Do not use the device or accessories if the packaging is wet, punctured, opened or
damaged because the integrity of the sterile packaging may be compromised. Return the
device to the manufacturer.
Device Storage:
Store the device in a clean area, away from magnets, kits containing magnets, and sources
of electromagnetic disturbance to avoid device damage. Store the device between 0 - 50 °C
(32 - 122 °F). Temperatures outside the specified range may damage the device.
Equilibration:
Allow the device to reach room temperature before programming or implanting the device
because rapid temperature changes may affect initial device function.
4.3.
IMPLANTATION AND DEVICE PROGRAMMING
Use only a Sorin programmer to communicate with the device.
Do not inadvertently position any magnet over the ICD; this suspends tachyarrhythmia
detection and treatment.
Replace the device when the RRT (Recommended Replacement Time*) point (defined by a
battery voltage of 2.66 ± 0.01 V or a magnet rate lower than or equal to 80 bpm) is reached.
Program device parameters such as sensitivity threshold and VT and VF detection intervals
as specified in the device manuals.
Lead System:
Do not use a lead system other than those with demonstrated compatibility because
undersensing cardiac activity and failure to deliver necessary therapy may result.
In situations where an ICD and a pacemaker are implanted in the same patient, interaction
testing should be completed. If the interaction between the ICD and the pacemaker cannot
be resolved through repositioning of the leads or reprogramming of either the pacemaker or
the ICD, the pacemaker should not be implanted (or should be explanted if previously
implanted).
Failure to properly insert the torque screwdriver into the perforation at an angle
perpendicular to the connector receptacle may result in damage to the sealing system and
its self-sealing properties.

SORIN – PLATINIUM SonR CRT-D – U463A
4. WARNINGS AND PRECAUTIONS
In the event of a warning on a low shock impedance, and after lead replacement or
reconnection: it is recommended to check the system integrity (sensing and pacing
thresholds and the impedance of the shock electrodes)
It is recommended that a security margin of at least 10 J be demonstrated between the
effective shock energy and maximum programmable energy. Carefully confirm that true
ventricular fibrillation has been induced because the DFT for ventricular tachycardia or flutter
may be lower.
The defibrillator should be implanted with the engraved side facing outwards in order to
facilitate telemetric communication with the programming head and to display the
radiographic identification correctly.
*: corresponds to ERI (Elective Replacement Indicator) previously used.
4.4.
LEAD EVALUATION AND LEAD CONNECTION
PLATINIUM SonR CRT-D 1811 has two DF-1, two IS-1, and one SonR connector ports. The
SonR connector port has been specifically designed by Sorin to accept three connections
(tripolar). The two distal connections respect the same dimensions as the IS-1 standard, and
an additional proximal connection allows to collect the SonR signal.
PLATINIUM SonR CRT-D 1841 has one DF4, one IS-1, and one SonR connector ports. The
SonR connector port has been specifically designed by Sorin to accept three connections
(tripolar). The two distal connections respect the same dimensions as the IS-1 standard, and
an additional proximal connection allows to collect the SonR signal.
The SonR port accepts either a conventional atrial lead (without SonR capability) or a SonR
atrial lead (bipolar pacing/sensing and SonR capability).
IS-1 refers to the international standard whereby leads and generators from different
manufacturers are assured a basic fit (ISO 5841-3:2013).
DF-1 refers to the international standard for defibrillation lead connectors (ISO 11318:2002).
DF4 refers to the international standard for defibrillation lead connectors (ISO 27186:2010).
Use only DF4-LLHH or DF4-LLHO standard lead connector types according to ISO 27186:
2010.
Do not tie a ligature directly to the lead body, tie it too tightly, or otherwise create excessive
strain at the insertion site as this may damage the lead. Use the lead stabilizer to secure the
lead lateral to the venous entry site.
Do not grip the lead with surgical instruments.
Do not use excessive force or surgical instruments to insert a stylet into a lead.
Use ventricular transvenous leads with caution in patients with either a mechanical or
bioprosthetic tricuspid valvular prosthesis.
Use the correct suture sleeve (when needed) for each lead, to immobilize the lead and
protect it against damage from ligatures.
Never implant the system with a lead system that has a measured shock impedance of less
than 30 ohms. A protection circuit in the defibrillator prevents shock delivery when
impedance is too low. If the shock impedance is less than 30 ohms, reposition the lead
system to allow a greater distance between the electrodes.
Do not kink leads. Kinking leads may cause additional stress on the leads, possibly resulting
in lead fracture.
Do not insert a lead connector pin into the connector block without first visually verifying that
the setscrews are sufficiently retracted. Do not tighten the setscrews unless a lead
connector pin is inserted because it could damage the connector block.

4. WARNINGS AND PRECAUTIONS
Lead electrodes in contact during a cardioversion or defibrillation therapy will cause current
to bypass the heart, possibly damaging the ICD and the leads. While the ICD is connected
to the leads, make sure that the metal portions of any electrodes do not touch each other.
If a pacing lead is abandoned rather than removed, it must be capped to ensure that it is not
a pathway for currents to or from the heart.
If a thoracotomy is required to place epicardial patches, it should be done during a separate
procedure to reduce the risk of morbidity and mortality.
Do not place the patch lead over nerve tissue as this may cause nerve damage.
Place the patch lead with the conducting coil side facing the heart to ensure delivery of
energy to the heart.
Place the sutures well outside the coil of the patch lead or in the area between the coils to
avoid possible coil fracture.
If countershock is unsuccessful using external paddles, adjust the external paddle position
(e.g., anterior-lateral to anterior-posterior) and be sure that the external paddle is not
positioned over the patch.
Do not fold, alter, or remove any portion of the patch as it may compromise electrode
function or longevity.
If a header port is unused on the generator, the port must be plugged to protect the
generator.
4.5.
GENERATOR EXPLANT AND DISPOSAL
Interrogate the device, and program shock therapy off prior to explanting, cleaning or
shipping the device to prevent unwanted shocks.
Return all explanted generators and leads to the manufacturer.
Never incinerate the device due to the potential for explosion. The device must be explanted
before cremation.

Clinical Results V-V timing
V-V programmable settings were available for the clinical study devices as follows: ALTO
MSP model 617 (not programmable for V-V delay), ALTO 2 MSP model 627 values (0, 31,
39, 47, 55 and 63 ms) and OVATIO CRT-D 6750 values (0 to 63 ms in steps of 8 ms).
The graph below shows the programmed V-V settings at randomization by percentage of
patients programmed to each combination of Synchronous BiV pacing and V-V delay.
The optimization protocol in the clinical study specified that each patient randomized should
undergo echo guided V-V optimization. Per the investigational plan for the MSP Clinical
18
SORIN – PLATINIUM SonR CRT-D – U463A
6. CLINICAL STUDIES
Trial, a uniform protocol was used for V-V programming. This protocol required all patients to
undergo echo-guided V-V delay optimization before randomization (2 to 14 days postimplant). The optimal V-V delay was determined by finding the programmable V-V delay and
ventricular chamber pacing order (RV then LV, or LV then RV) providing the maximum time
velocity integral (TVI or VTI) across the left ventricular outflow tract (LVOT).
Only those patients randomized to the Test arm were required to be programmed per the
optimization protocol for the V-V delay.
Of the 177 patients that presented at randomization, 3 had Model 617 which does not have
V-V programmability hence the inability to optimize. Of the remaining 174 patients, 154
(89%) were tested per the V-V optimization protocol. One hundred forty-nine (149) of the
154 patients who were tested per the V-V optimization protocol were programmed per the
recommended or randomized V-V delay (97%). Thirty-one (31) patients were programmed
to BiV synchronous (V-V delay 0ms), 46 were programmed to Sequential BiV (LV then RV),
22 were programmed to Sequential (RV then LV), and the remaining 50 patients were
randomized to RV only.
A sub-analysis of the composite endpoint comparing the subset of CRT-D patients with
optimized V-V delays vs. the subset of patients that did not undergo V-V delay optimization
demonstrated similar results in both groups. The CRT-D patients who did not undergo V-V
delay optimization showed a smaller improvement in the composite endpoint, although the
sample size did not permit conclusions based on data from this subset.

7. PATIENT SELECTION AND TREATMENT
7. PATIENT SELECTION AND TREATMENT
7.1.
INDIVIDUALIZATION OF TREATMENT
Exercise stress testing:
If the patient’s condition permits, use exercise stress testing to:
─
Determine the maximum rate of the patient’s normal rhythm,
─
Identify any supraventricular tachyarrhythmias,
─
Identify exercise-induced tachyarrhythmias.
The maximum exercise rate or the presence of supraventricular tachyarrhythmias may
influence selection of programmable parameters. Holter monitoring or other extended ECG
monitoring also may be helpful.
CAUTION: To avoid inappropriate therapy during an exercise stress test, do not reprogram
any parameter during the test. When a parameter is reprogrammed, algorithm forces
acceleration to "ventricular". During conducted sinus tachycardia within the programmed
Tachy zone, the device detects a 1:1 fast rhythm. Assuming that acceleration was set to
ventricular by reprogramming, the device may identify this as a VT, and may immediately
apply the corresponding therapy.
Electrophysiologic (EP) testing:
EP testing may be useful for ICD candidates.
EP testing may identify the classifications and rates of all the ventricular and atrial
arrhythmias, whether spontaneous or during EP testing.
Drug resistant supraventricular tachyarrhythmias (SVTs):
Drug resistant supraventricular tachyarrhythmias (SVTs) may initiate frequent unwanted
device therapy.
A careful choice of programming options is necessary for such patients.
Antiarrhythmic drug therapy:
If the patient is being treated with antiarrhythmic or cardiac drugs, the patient should be on a
maintenance drug dose rather than a loading dose at the time of ICD implantation. If
changes to drug therapy are made, repeated arrhythmia inductions are recommended to
verify ICD detection and conversion. The ICD also may need to be reprogrammed.
Changes in a patient’s antiarrhythmic drug or any other medication that affects the patient’s
normal cardiac rate or conduction can affect the rate of tachyarrhythmias and/or efficacy of
therapy.
Direct any questions regarding the individualization of patient therapy to Sorin’s
representative.

13. DEVICE DESCRIPTION
13. DEVICE DESCRIPTION
The PLATINIUM SonR CRT-D ICD device and programming system. The programming
system includes the Sorin dedicated programmer with the SMARTVIEW programming
software connected to a CPR3 programming head. The programming system is configured
and furnished by Sorin.
The PLATINIUM SonR CRT-D can serve as a defibrillation electrode (active housing) with a
total surface area of 63 cm².
The PLATINIUM SonR CRT-D is designed to recognize and treat slow or fast VT and VF by
continuously monitoring atrial and ventricular activity to identify persistent ventricular
arrhythmias and to deliver appropriate therapies. PLATINIUM SonR CRT-D features the
PARAD/PARAD+ algorithm, which is specifically designed to differentiate ventricular
tachycardias from fast rhythms of supraventricular origin. PARAD/PARAD+ continuously
monitors R-R interval stability, searches for long cycles, assesses the degree of P-R
association, evaluates sudden onset and determines the chamber of arrhythmia
acceleration.
In addition to the advanced detection scheme, PLATINIUM SonR CRT-D offers
programmable single, dual or triple-chamber pacing therapy (DDD, DDI, VVI or SafeR (AAI
<> DDD) modes) with or without rate-responsive capabilities (DDDR, DDIR, VVIR,
DDD/DDIR and SafeR-R (AAIR <> DDDR) modes) using an acceleration sensor. An
automatic AV delay algorithm as well as a mode switching function are available.
PLATINIUM SonR CRT-D enables an adjustment of the interventricular delay, and provides
the possibility of adapting pacing to each ventricle. The ICD is intended to resynchronize
uncoordinated contraction of the heart by simultaneously or sequentially pacing both
ventricles.
PLATINIUM SonR CRT-D offers tiered therapy. Therapies can be programmed
independently in each zone:
─
in the Slow VT and VT zones: two ATP programs, up to two shocks with programmable
energy and up to four shocks with maximum energy can be programmed;
─
in the VF zone: one ATP program, up to two shocks with programmable energy and up
to four shocks with maximum energy can be programmed.
The ATP can be applied in RV, LV or RV and LV pacing with a VV delay equal to 0 ms. ATP
pacing configuration is independent of ventricular pacing configuration.
When the rhythm changes from one zone to another, the device delivers the therapy
programmed in this zone, starting with the same or more aggressive program for the area.
The ATP program in the VF zone will only be applied if the VT coupling interval is longer
than the programmed fast VT cycle length.
The PLATINIUM SonR CRT-D offers biphasic shocks with a maximum stored energy of 42 J.
The shock configuration (electrodes used to apply the shock) can be chosen by
programming one of the following combinations: can and one coil, can and two coils, two
coils only.
Other features are as follows:
─
Automatic ventricular sensitivity control
─
Non-committed shocks
─

14. IMPLANT PROCEDURE
14.4.
BEFORE OPENING THE PACKAGE
Before opening the package, check the "Use Before" date printed on the labels on the box
and on the sterile package. Defibrillators that have not been implanted before that date
should be returned to Sorin.
Interrogate the device:
─
if a warning is displayed, do not implant the device and contact your Sorin
representative.
─
if battery voltage is below 3V, and if the last reforming/charge occurred more than one
week ago, do not implant the device. Otherwise wait for one more week before checking
the voltage.
NOTE : The battery voltage can decrease before the expiration date is reached. However,
the battery voltage should be equal to or higher than 3V at the time of implant.
Devices MUST NOT be interrogated and programmed within the vicinity of other devices.
Also check the integrity of the sterile package. The sterility of the contents is no longer
guaranteed if the package has been pierced or altered. If the defibrillator is no longer sterile,
it should be returned in its packaging to Sorin. Any re-sterilization of the unit is at the
discretion of Sorin.
14.5.
PRIOR TO IMPLANTATION
Use the programmer to verify the defibrillator can be interrogated before implantation.
Verify all shock therapies are disabled in order to avoid accidental discharge during
implantation.
It is not advisable to program the Smoothing function before implantation, since the
defibrillator may detect noise and pace at a rate higher than the programmed basic rate.
CAUTION:
Do not shake or tap sharply on the ICD package with the ICD inside, because the ICD's
sensing circuits can interpret this as P-waves or R-waves and record these as an arrhythmia
episode.
High voltage capacitors charge performed on ICD without connected leads using wireless
telemetry can generate false P-waves or R-waves detection.
It is recommended to reset the memory data and statistics before implanting the ICD.
14.6.
DEVICE PLACEMENT
The pocket should be prepared in the left pectoral position, either subcutaneously or
submuscularly. Subcutaneous device implantation is recommended for optimal RF
communication efficacy.
Implantation in an abdominal position is not advisable.
In its final position, the defibrillator should be no more than 4 cm below the skin surface.
14.7.
CHOOSING THE TYPE OF LEAD
The defibrillator should be connected to:
32
─
one bipolar atrial sensing/pacing lead with or without dedicated SonR sensor
─
one right ventricular lead with bipolar sensing/pacing electrodes and one or two
SORIN – PLATINIUM SonR CRT-D – U463A
14. IMPLANT PROCEDURE
defibrillation coils
─
one unipolar or bipolar left ventricular pacing lead
The choice of leads and their configuration is left to the implanting physician’s judgment.
Replacement of an existing atrial lead:
If the initial lead which was connected to the atrial port of the PLATINIUM SonR CRT-D was
not a SonR lead (i.e. a conventional lead or plug), then do not implant a SonR lead as
replacement; possible blood infiltration at the entrance of the connector port may prevent
proper measurement of the SonR signal.
NOTE1: Please note that DF-1 standard compliant lead is not compatible with DF4
connector. In the reverse, DF4 standard compliant lead is not compatible with DF-1
connector. In case of defibrillator replacement, choose the appropriate device compatible
with DF-1 or DF4 leads. For any other lead type that requires an adaptor for this device,
please contact your Sorin representative for any information on lead / connector
compatibility question.
NOTE2: In the event that no atrial lead is implanted, the atrial port should be plugged with
IS-1 insulating plug and a single chamber mode (VVI-VVIR) should be programmed. PARAD
and PARAD+ should not be used.
NOTE3: In the event of a warning on a low shock impedance, and after lead replacement or
reconnection: it is recommended to check the system integrity (sensing and pacing
thresholds and the impedance of the shock electrodes).
Connectors:
PLATINIUM SonR CRT-D 1811:
The pacing/sensing connectors are compatible with the IS-1 standard and the right
ventricular defibrillation connectors are compatible with DF-1 standard.
PLATINIUM SonR CRT-D 1841:
The atrial and left ventricular connectors are compatible with the IS-1 standard and the
quadripolar right ventricular connector is compatible with the DF4 standard.
14.8.
SHOCK CONFIGURATION (+ -> -)
The shock configuration is the energy pathway between the defibrillation electrodes. If an
atrial coil is present, the shock configuration can be programmed for bi-directional shocks.
Programming:
When active case and SVC are both programmed to Yes, the shock configuration can be
programmed to:
─
RV to Case (or Case to RV),
─
or RV to SVC (or SVC to RV),
─
or RV to Case+SVC (or Case+SVC to RV).

The polarity of shock is determined by the parameter itself.
14.9.
MEASUREMENT OF THRESHOLDS AT IMPLANT
Pacing and sensing thresholds should be measured at implant.
Pacing thresholds:
Acute thresholds should be lower than 1 V (or 2 mA) for a 0.35 ms pulse width, in both
ventricles and in the atrium.
Sensing thresholds:
For appropriate right ventricular sensing, the amplitude of the R-wave should be greater
than 5 mV.
For appropriate atrial sensing, the amplitude of the P-wave should be greater than 2 mV.
Pacing impedance measurements:
Right ventricular, left ventricular and atrial pacing impedances should range from 200 to
3000 ohms (refer to the lead characteristics, especially if high impedance leads are used).
Please refer to the leads user manuals for more details on the expected electrical
performances of the leads.
14.10.
LEADS CONNECTION
Implant the ventricular leads, then the atrial lead.
Each lead must be connected to the corresponding connector port. The position of each
connector is indicated on the casing.
CAUTION:
Tighten only the distal inserts.
To connect each lead, proceed as follows:
1. Clean the lead terminal pins thoroughly, if necessary (device replacement).
2. Lubricate the lead terminal pins with sterile water, if necessary.
3. Do not insert a lead connector pin into the connector block without first visually verifying
that the lead port is not filled with any obstacle.
4. Insert the screwdriver into the pre-inserted screw socket of the appropriate port (in order
to allow excess air to bleed out and to make the insertion of the lead pin easier).
5. Insert the lead pin all the way into the port (check that the pin protrudes beyond the distal
insert).

6. Tighten, check the tightness and ensure the lead pin still protrudes beyond the distal
insert, and has not move.
CAUTION:
1. Do not tighten the pre-inserted screws when there is no lead (this could damage the
connector).
2. Do not loosen the screws before inserting the connector (subsequent risk of being unable
to reinsert the screw).
3. When mineral oil or sterile water is used to make lead insertion easier, the screwdriver
should remain inserted into the pre-inserted screw socket when checking the tightness.
As a matter of fact, when the lead port is filled with a liquid, the physics piston effect can
give the feeling the lead is properly tightened.
4. One single set screw is located on the side of the connection header.
5. Use only the screwdriver provided with the defibrillator. Keep the screwdriver's shaft
perpendicular to the plane of the defibrillator (see figure below).
6. Removing the screwdriver: to avoid all risk of loosening screws during removal, hold the
screwdriver by its metal part and not by the handle.
WARNING: Ensure that the screwdriver's tip is fully inserted in the setscrew; otherwise the
screwdriver can damage the setscrew and prevent connection with or disconnection from
the lead.
To ensure full insertion, push the screwdriver's hex tip smoothly into the setscrew until it
reaches the bottom of the hex chamber in the screw, which can be felt as a solid metallic
contact. Do not implant the defibrillator if there is no feeling of solid metallic contact. Do not
implant the defibrillator if the wrench does not click when attempting to tighten the setscrew
on the lead pin.
NOTE: To optimize cardioversion/defibrillation shocks, electrodes must be positioned so that
the electric field between anode(s) and cathode covers the largest myocardial mass. In
normal conditions, the anode and cathode are adequately separated. In case of a shortcircuit, the shock may be aborted to prevent damaging the defibrillator.
In the case of an external defibrillation shock delivered to the patient, always check the
programming and functioning of the device, in particular its capacity to deliver shocks.

14.11.
DEVICE IMPLANTATION
PLATINIUM SonR CRT-D should be implanted with the device identification engraved side
facing outwards for optimal communication with the programming head and radiographic
identification.
Carefully wind excess lead and place in a separate pocket to the side of the defibrillator.
It is recommended not to place any excess wire between the can and the heart.
Suture the casing connector to the muscle using the hole provided for this purpose, in order
to avoid potential migration of the device into the pectoral muscle.
14.12.
TESTS AND PROGRAMMING
During the implant testing procedure:
It is recommended that a security margin of at least 10 J be demonstrated between the
effective shock energy and maximum programmable energy.
Enable shock therapies, then program the defibrillator.
Verify that the defibrillation lead impedance for each shock delivered is within the range of
30 to 150 ohms. Check the lead connection if the values are outside these boundaries.
Save the programming data on the programmer’s hard disk and on an external storage
device (if desired).
Resuscitation Availability:
Do not perform device testing unless an external defibrillator is available and medical
personnel skilled in cardiopulmonary resuscitation (CPR) are present.
Disable the ICD During Handling:
Program Shock Therapy to OFF during surgical implant and explant or post mortem
procedures. The device can deliver a serious high energy shock should accidental contact
be made with the defibrillation electrodes, the device can deliver a very high energy shock.

15.1.
SAFETY MODE (NOMINAL VALUES)
Nominal values may be rapidly restored by pressing the following button on the
programming head or programmer keyboard:
or via the Emergency button on the SMARTVIEW screen.
In safety mode, the defibrillator operates with the parameters underlined in the table of
programmable parameters.
15.2.
MAGNET MODE
When the magnet is applied:
─
antiarrhythmia functions are inhibited (detection of rhythm disturbances, charging, and
therapy),
─
hysteresis, VV delay and AVD paced/sensed offset are set to 0,
─
pacing amplitude is set to 6 V,
─
pulse width is set to maximum,
─
the following functions are disabled: ventricular arrhythmia prevention, Mode Switch,
Anti-PMT, Smoothing, Rate Response.
When the magnet is removed:
─
arrhythmia detection algorithms and sequential therapies are reinitialized,
─
therapies start with the least aggressive program for each area.
The antiarrhythmia functions inhibition is extended after magnet removal if a charge
occurred just before the application of the magnet in order to ease the communication
between the device and the programmer.
The other parameters remain at their programmed value, including the ventricular paced
chamber parameter.
15.3.
RESPONSE IN THE PRESENCE OF DISTURBANCE
If the defibrillator senses electrical noise at a frequency above 16 Hz, it switches to an
asynchronous mode at the basic rate. The programmed mode is restored as soon as the
noise is no longer detected.
Ventricular pacing may also be inhibited by ventricular noise. It can be restored by setting
the parameter V pacing on noise to Yes.
15.4.

PROTECTION AGAINST SHORT-CIRCUITS
The defibrillator can undergo a short-circuit if the anode and cathode are not adequately
separated.
In this case, the shock is aborted to prevent damaging the defibrillator and a warning will
indicate that a short circuit (shock impedance < 20 ohms) was detected during the last
shock.

16. MAIN FUNCTIONS
16. MAIN FUNCTIONS
16.1.
AUTOMATIC LEAD MEASUREMENTS
Automatic pacing lead impedance measurement:
A lead impedance measurement is automatically performed on atrial and ventricular leads
every 6 hours. The daily mean impedance is stored for each chamber.
Automatic coil impedance measurement:
A continuity measurement is automatically performed on defibrillation coil(s) once per day.
The continuity is stored for each coil.
Automatic sensing measurement:
The amplitude of P and R waves are automatically measured at each cycle. Every 8.5
minutes, the amplitude of the last 8 P and R detections are averaged and stored.
16.2.
ATRIAL TACHYARRHYTHMIA MANAGEMENT
Mode Switch:
This function is designed to limit the acceleration and variation of ventricular rate in the
presence of atrial arrhythmia.
16.3.
VENTRICULAR TACHYARRHYTHMIA MANAGEMENT
Ventricular tachyarrhythmia prevention:
Set of algorithms that can be used to avoid the circumstances of ventricular tachyarrhythmia
onset.
Arrhythmia discrimination algorithm PARAD and PARAD+ (P And R based Arrhythmia
Detection):
PARAD is the algorithm used to discriminate sinus tachycardias (ST) and supraventricular
tachycardias (SVT) from ventricular tachycardias (VT).
PARAD+ is based on the PARAD algorithm but additionally takes into account the
“AFdetect” discrimination criteria: the occurrence of a "long ventricular cycle" characteristic
for AF patients which is an additional arrhythmia classification criterion to improve
identification of atrial fibrillation and avoid inappropriate shocks.
Fast VT treatment:
Applies detection criteria on fast ventricular tachycardia that are different from those of the
VT zone, as well as different therapies. The fast VT zone is included in the VF zone: its
lower limit is determined by the programmed value for the VF zone and its upper limit by the
programmed value for the fast VT zone.
Polarity alternation on Max shock:
Reverses the programmed polarity of every second shock set at maximum energy. The
number, type, and energy of shocks is independently programmable by detection zone.
40
SORIN – PLATINIUM SonR CRT-D – U463A
16. MAIN FUNCTIONS
Defibrillation threshold (DFT):
Be aware that the changes in the patient’s condition, drug regimen, and other factors may
change the defibrillation threshold (DFT) which may result in non-conversion of the
arrhythmia post-operatively. Successful conversion of ventricular fibrillation or ventricular
tachycardia during arrhythmia conversion testing is no assurance that conversion will occur
post-operatively.
16.4.
PACING
BTO (Brady Tachy Overlap):
Enables cardiac resynchronization therapy within the slow VT zone to preserve patient
exercise capacity, without affecting detection or treatment of slow VTs.
Post-shock mode:
After any automatic shock therapy, the post-shock mode makes it possible to apply a pacing
mode other than the standard antibradycardia pacing mode and/or with different pacing
parameters.
SafeR (AAI <> DDD) mode:
Is intended to minimize deleterious effects of ventricular pacing. The defibrillator functions in
AAI mode, and temporarily switches to DDD mode upon the occurrence of AVB III, AVB II,
AVB I and ventricular pause.
Anti-PMT protection:
Is intended to protect the patient from Pacemaker-Mediated Tachycardia (PMT) without
reducing atrial sensing capability of the device.
16.5.
SENSING
Automatic Refractory Periods:
Optimize sensing and make the implant programming easier. These periods are composed
of a minimal Refractory Period and a triggerable Refractory Period. The duration of the
refractory periods lengthens automatically as needed.
Committed period:
In DDI or DDD modes, the committed period is a non-programmable 95 ms ventricular
relative refractory period that starts with atrial pacing. If a ventricular event is sensed during
the committed period, but outside the blanking period, the ventricle is paced at the end of
the committed period. The committed period prevents inappropriate ventricular inhibition if
crosstalk occurs.
Protection against noise:
Allows the distinction between ventricular noise and ventricular fibrillation. If the device
senses ventricular noise, the ventricular sensitivity is decreased until noise is no longer
detected. Ventricular pacing can be inhibited to avoid a potential paced T-wave.
Automatic sensitivity control:
Optimizes arrhythmia detection and avoids late detection of T-waves and over-detection of
wide QRS waves. The device automatically adjusts the sensitivities based on the ventricular
sensing amplitude. In case of arrhythmia suspicion or after a paced event, the programmed
ventricular sensitivity will be applied. The minimum ventricular sensitivity threshold is 0.4 mV
(minimum programmable value).
SORIN – PLATINIUM SonR CRT-D – U463A
41
16. MAIN FUNCTIONS
16.6.
SONR CRT OPTIMIZATION
SonR is a specific sensor, located at the tip of the atrial lead, that picks-up microaccelerations of the heart walls to derive information pertaining to cardiac contractility. The
signal picked-up by the SonR sensor can be processed by PLATINIUM SonR CRT-D in
order to automatically adjust VV delays and AV delays during rest and exercise for optimal
resynchronization therapy. In addition, the SonR signal is recorded during tachyarrhythmia
episodes to depict acute variations of cardiac contractility. PLATINIUM SonR CRT-D can
also transmit real-time SonR signals via telemetry.
16.7.
FOLLOW-UP FUNCTION
Storage of memory data:
AIDA+ (Automatic Interpretation for Diagnosis Assistance) software provides access up to 6
months of patient follow-up with day by day data collection, or up to 24 hours with hourly
data collection. Episodes of ventricular tachyarrhythmia are recorded with one
programmable EGM channel which can be selected, in addition to RV EGM.
Alerts / Warnings:
The device routinely performs security self-checks and technical measurements to ensure
system integrity. When system integrity is found to be at risk outside a follow-up, alerts are
stored in the device memory. When system integrity is found to be at risk during a follow-up,
the information is managed by a warning (pop-up message) to immediately notify the user.
For example, the following types of event can trigger a warning or an alert: technical
problem during a shock, lead impedance or shock continuity measurements out-of-range,
battery depletion, …
16.8.
REMOTE MONITORING FUNCTION
Remote monitoring enables the automatic remote transmission of implant data to the
physician thanks to the wireless Radio Frequency (RF) communication ability of the implant
in order to provide a comprehensive report to the physician about device functioning and
patient cardiac status without having the patient physically in the clinic.
The data is transmitted from the implant to the SMARTVIEW monitor, a small transmitter
placed in the patient's home.
Implant data are first transmitted to the SMARTVIEW monitor via RF. Data are then rooted
through the phone line or via GPRS to an internet website. This website is responsible for
transforming the implant data into a comprehensive report that can be consulted by the
physician.
16.8.1.
SMARTVIEW Monitor
The SMARTVIEW monitor is a small device equipped with an RF transmission module to
communicate with the implant and a modem to export data through the internet.
The SMARTVIEW monitor is delivered to the patient who has to install it at home. Preferably
the SMARTVIEW monitor will be placed on the nightstand of the patient, as close as
possible to the side of the bed where the patient usually sleeps. The SMARTVIEW monitor
connects to the phone line of the patient and the power plug. Regular transmissions are
done during the night when the patient is asleep next to the SMARTVIEW monitor without
any intervention from the patient.

Transmission trigger
There are 3 different triggers for a remote transmission:
─
the remote follow-up transmission is scheduled by the physician to occur regularly
(according to the programming).
─
the alert transmission will take place when the implant has recorded an abnormal
event. The list of abnormal event is available in a following paragraph. Alert conditions
are checked daily.
─
the on-demand follow-up transmission is triggered by the patient himself through the
use of a specific button on the SMARTVIEW monitor.
16.8.3.

FOLLOW-UP RECOMMENDATIONS
Before the patient is discharged and at each subsequent follow-up visit, it is advisable to:
─
check the occurrence of system warnings
─
check the battery status,
NOTES:
If the last reforming, charge or shock occurred during the week preceding the interrogation,
the last battery value may be still impacted by the event. One week post event, the battery
will recover its steady state value.
Automatic capacitor charging may affect communication between the device and the
programmer.
─
check the integrity of the pacing and defibrillation leads,
─
check for proper sensing (sensitivity, crosstalk) and pacing ; set the pacing amplitude to
twice the pacing threshold,
─
interrogate the implant memories (AIDA+),
─
check the efficacy of the therapies delivered,
─
keep a printout of programmed parameters, test results, and memory data,
─
reset the memory data and statistics.
These operations should be performed by medical personnel in an appropriate care unit,
with resuscitation equipment present.
It is recommended that a routine follow-up examination be done one month after discharge,
and then every three months until the device nears the replacement date.
Refer to the online help for a description of displayed warning, and the necessity to contact
Sorin for an evaluation.
Implant software upgrade:
In case a new implant software is downloaded in the device memory through the
programmer, a warning message could be displayed by the programmer to inform the user
and give the correct instructions to follow.

Stored Tachyarrythmia Episodes:
PLATINIUM SonR CRT-D stores up to 16 episodes (VF, VT, Slow VT, SVT/ST, nonsustained) with a total of 25.6 min of high resolution EGM and 5 min of SonR signal.
For each episode four levels of details are presented:
─
Tachogram (to visualize PP and PR intervals)
─
Event log for the entire episode:
─ PARAD/PARAD+ analysis for each majority,
─ Delivered therapies,
─
Markers: Atrial, ventricular and biventricular markers, sensed, paced and in relative

rhythm by recording electrogram.
Therapy history
For each arrhythmia detection, each therapy delivered (either automatically or during an
electrophysiological study) and at the end of each arrhythmia, PLATINIUM SonR CRT-D
records the type of majority rhythm, the number of ATP sequences delivered, the energy and
the number of shocks delivered.
17.3.
RECOMMENDED REPLACEMENT TIME (RRT)
Recommended Replacement Time (RRT)(1) is controlled by: battery voltage equal to 2.62 V
± 0.01 V
CAUTION: The defibrillator should be replaced as soon as the Recommended Replacement
Time (RRT) point is reached.
Between the RRT and the EOS (End of Service) (2), PLATINIUM SonR CRT-D can still
function for:
─
10.8 months (100% atrial and biventricular pacing in DDD mode, 500 ohms, with asshipped settings), and deliver 11 shocks at 34 J or
─
10,4 months (0% pacing, sensors OFF, one shock every 2 weeks) and deliver 21 shocks
at 34 J.
Once the Recommended Replacement Time (RRT) point has been reached, the device
operates normally, except that the charge time increases. Under normal conditions (and
without programmer use) the charge times are as follows:
Shock energy

EXPLANTATION
The defibrillator should be explanted in the following cases:
46
SORIN – PLATINIUM SonR CRT-D – U463A
17. PATIENT FOLLOW-UP
─
The Recommended Replacement Time (RRT) point is reached
─
Confirmed malfunction
─
Burial of the patient (for environmental reasons, the local regulation may require the
explantation of the devices containing a battery supply)
─
Cremation of the patient (the defibrillator may explode if placed in an incinerator)
The explanted defibrillator should not be reused in another patient.
All explanted defibrillators should be returned to Sorin, carefully cleaned of all traces of
contamination. Cleaning may be done by immersing them in an aqueous sodium
hypochlorite containing at least 1% chlorine, followed by rinsing copiously with water.
The defibrillator should be protected against mechanical impact and the temperature
variations that may occur during shipping.
Before explantation, it is advisable to:
17.5.
─
Print out all programmed parameters, statistics and Holter function report,
─
Save Patient data on floppy disk or hard disk,
─
Disable shock therapies (VT and VF) to avoid any risk of untimely shock.
DEFIBRILLATOR IDENTIFICATION
The defibrillator can be interrogated and programmed via telemetry, using the programming
head interfaced with the Sorin dedicated programmer.
Position the programming head over the telemetry antenna located in the upper part of the
device, in order to communicate effectively via telemetry (see diagram below).
The device can be non-invasively identified as follows:
1. Take an x-ray to identify the name of the manufacturer and model, printed on the device
(X-ray ID is SEA for PLATINIUM range).
2. Interrogate the device using the Sorin dedicated programmer. The model and serial
number of the device are automatically displayed. The first figure in the serial number
corresponds to the last figure in the year of manufacture.

symptoms were associated with these events.
18.2.
SAFER (AAI <> DDD) CLINICAL STUDY
SafeR (AAI <> DDD) mode in PLATINIUM is similar to that in Symphony.
The differences in SafeR (AAI <> DDD) mode between the two devices are:
─
To prevent long RR intervals during VT/VF, SafeR (AAI <> DDD) has no effect during
VT/VF therapy, electrophysiologic studies, and post-shock recovery.
─
The maximum acceptable AV delay for first degree AV block varies as a function of
pacing rate.
─
PLATINIUM requires a ventricular sensed event to atrial paced event (RA) interval of at
least 100 ms. Therefore, the device lengthens the atrial escape interval so that it ends at
least 102 ms after the ventricular event.
─
During atrial fibrillation episode, pause criterion is fixed to 2s to avoid long bradycardia
episodes in switching to DDD mode.
Despite these differences, the data collected on Symphony devices are applicable to
PLATINIUM because the principles of SafeR (AAI <> DDD) operation did not change. The
criteria for switching from AAI to DDD (or vice versa) did not change. The device’s method
for evaluating the presence of AV conduction did not change.
Methods:
All patients were implanted with a Symphony Model 2550 dual-chamber rate-responsive
pacemaker with SafeR (AAI <> DDD) mode. A variety of marketed atrial and ventricular
pacing leads were used. The pacemaker was programmed and interrogated via bidirectional telemetry using a Sorin dedicated programmer and a CPR3 programming head.
The study’s routine evaluation consisted of enrollment, pre-discharge evaluation, and a
scheduled follow-up visit at one month. At pre-discharge, a 24-hour Holter recording was
performed and pacemaker memory was read. At one month, pacemaker memory was read.
Investigators also documented adverse events.
Patients studied:
A total of 45 patients from 12 centers had Symphony 2550 pacemakers with SafeR (AAI <>
DDD). Of these, 14 (31 %) were female and 31 (69 %) were male. Mean patient age (± SD)
was 74 ± 9 years.
Primary indications for implant were: 1st degree AV block (11.1 %), 2nd degree AV block (6.7
%), 3rd degree AV block (22.2 %), sinus node dysfunction (62.2 %) or other (6.7 %).
Effectiveness results:
To determine the effectiveness of SafeR (AAI <> DDD) mode, the percentage of ventricular
pacing provided over one month was recorded from pacemaker memory.
Thirty-five patients contributed data to evaluate the percentage of ventricular pacing
provided with SafeR (AAI <> DDD). Twenty-nine patients had 1 % or less ventricular pacing
and six patients had a range of 28-97 % ventricular pacing. The graph below shows the
distribution of ventricular pacing observed in patients with and without AV block as a primary
indication for implant.
SORIN – PLATINIUM SonR CRT-D – U463A
49
18. SUPPLEMENTAL INFORMATION
The graph shows that many patients programmed to SafeR (AAI <> DDD) had less than 1%
ventricular pacing:
─
84 % of patients without AV block at implant.
─
63 % of patients with AV block at implant.
In a representative reference group(1) of patients programmed to DDD, none had less than 1
% ventricular pacing and only 10 % had less than 90 % ventricular pacing regardless of AV
block indication at implant.
The actual reduction of ventricular pacing that SafeR (AAI <> DDD) provides in an individual
will depend on the amount of time that the patient spends in AV block. SafeR (AAI <> DDD)
cannot and should not provide any decrease in ventricular pacing while the patient is in AV
block.

1h of additional RF programming session reduces the device longevity from 1 to 2 weeks
depending on the device functioning mode (no pacing, 100% pacing). The mean longevity
as a function of shocks delivered at maximum energy, with and without pacing, is as follows:
The mean longevity as a function of yearly remote follow-ups 1, with and without pacing, is as
follows:
1. An excessive number of remote follow-ups can have a non-negligible impact on device
longevity.

REMOTE ALERTS AND WARNINGS
The device routinely performs security self-checks and technical measurements to ensure
system integrity. When system integrity is found to be at risk outside a follow-up, alerts are
stored in the device memory. When system integrity is found to be at risk during a follow-up,
the information is managed by a warning (pop-up message) to immediately notify the user.
For example, the following types of event can trigger a warning or an alert: technical
problem during a shock, pacing lead impedance or coil impedance measurements out-ofrange, battery depletion, etc. The Remote tab presents an overview of all the alerts
managed by the device.
