Background: Extra-vascular implantable cardioverter defibrillator (EV-ICD) is an emerging technique for ICD implantation with substernal lead placement. The system avoids the vasculature and can deliver anti-tachycardia and pause prevention pacing, with a generator size smaller than the existing subcutaneous device. While this device is now widely available, little is known about potential complications that may follow its implantation in real life context.

The Extravascular ICD (EV-ICD) is implanted outside of the patient's heart and vascular system. The defibrillation lead is tunneled in the substernal space, very close to the surface of the heart, thus allowing for additional pacing capabilities such as Post Shock Pacing, Anti-Tachycardia Pacing (ATP), and Pause Prevention Pacing. Early studies demonstrated the safety and efficacy profile of the EV-ICD, but patients with previous or existing cardiac devices or leads were excluded.

Extravascular implantable cardioverter-defibrillators (EV-ICD) offer defibrillation, anti-tachycardia pacing (ATP), and backup pacing, packaged in a unit comparable to traditional transvenous ICDs in size, shape, and longevity. However, the pacing capabilities of EV-ICD are restricted to ATP, pause prevention and post-shock pacing. For EV-ICD patients who develop the need for pacing, having a concomitant leadless pacemaker such as Micra could provide the needed pacing support.

Background: The extravascular implantable cardioverter-defibrillator (ICD) has a single lead implanted substernally to enable pause-prevention pacing, antitachycardia pacing, and defibrillation energy similar to that of transvenous ICDs. The safety and efficacy of extravascular ICDs are not yet known.
Methods: We conducted a prospective, single-group, nonrandomized, premarket global clinical study involving patients with a class I or IIa indication for an ICD, all of whom received an extravascular ICD system.
