An entirely subcutaneous implantable cardioverter–defibrillator.

BACKGROUND Implantable cardioverter-defibrillators (ICDs) prevent sudden death from cardiac causes in selected patients but require the use of transvenous lead systems. To eliminate the need for venous access, we designed and tested an entirely subcutaneous ICD system. METHODS First, we conducted two short-term clinical trials to identify a suitable device configuration and assess energy requ...

Subcutaneous implantable cardioverter-defibrillator.

or nearly 3 decades, the implantable cardioverter-defibrillator (ICD) has been available to patients who survived life-threatening rapid heart rhythms or are at risk of experiencing them. The ICD comprises a device generator coupled with a defibrillation lead. Traditional ICDs are implanted under the skin with the generator positioned beneath the collar bone. The defibrilla-tion lead is inserte...

Implantation of the Subcutaneous Implantable Cardioverter-Defibrillator

The subcutaneous implantable cardioverter-defibrillator (S-ICD) was introduced to reduce acute transvenous leadrelated complications, such as pneumothorax, endocarditis, cardiac perforation, and lead dislodgements, as well as the complications related to chronic indwelling leads, such as lead failure, venous obstruction, and bacteremia. The standard implantation technique of the S-ICD involves ...
