2.1 ASSESSINGTHEACOUSTICWINDOW
An acoustic window is commonly known in echocardiography as the location where a transthoracic
echocardiography(TTE) probe is placed to view the heart. The term “window”refers a lung‐free,cartilage‐free
pathwayforultrasoundtotravelbetweentheprobeandtheheart.
TheWiSECRTTransmittersendsultrasonicpulsesthroughthechestwalltotheElectrodeintheheartandthusmust
beimplantedinanadequateacousticwindow(atleast1cmspacingbetweencostalcartilages1by2.5cmwide)for
transmission of ultrasound. This window is typically in the 5thor6
th intercostal spaces (ICS), lateral to the left
parasternalborder.Howeverduetoanatomicalvariabilityoccasionallythe4thor7thICSmaybeused.

considered.Foroptimaltransmission,thedistanceshouldbe10cmorlesswithatransmissionangle(bothmedial‐
lateral angle and cranial‐caudal angle) less than 30 degrees. Positioning the Transmitter as medial as possible
minimizes the possibility of reduced performance due to lung encroachment and should always be a primary
objective,regardlessoftheacousticwindowselected.TheICSwithlargerdimensionsshouldbefavored.
