Implantable Defibrillator Therapy for Ventricular Tachyarrhythmia in Left Ventricular Assist Device Patients

Abstract

Implantable cardioverter-defibrillator therapy is safe and effective in LVAD patients. Ventricular arrhythmias leading to ICD intervention occur frequently in 34% of LVAD patients after 1 year, with large variations depending on the underlying cardiac disease and previous arrhythmia history. Primary prevention ICD indication after LVAD implantation yields high rates of ICD intervention. A history of previous VA strongly predicts future use of ICD treatment after LVAD implantation.
