ABSTRACT The extravascular implantable cardioverter-defibrillator (EV-ICD) was developed to overcome complications associated with transvenous leads while being able to deliver anti-tachycardia pacing (ATP). The lead is implanted in the substernal space, which makes extraction a cautious procedure.

However, ventricular arrhythmias (VA) are common, are mostly secondary to underlying myocardial scar, and have a higher incidence in patients with pre-LVAD VA.
