The development of the extravascular defibrillator with substernal lead placement: A new Frontier for device‐based treatment of sudden cardiac arrest

The extravascular implantable cardioverter‐defibrillato (EV ICD) system with substernal lead placement is a novel nontransvenous alternative to current commercially available ICD systems. The EV ICD provides defibrillation and pacing therapies without the potential long‐term complications of endovascular lead placement but requires a new procedure for implantation with a safety profile under evaluation.
