Catheter Ablation of Ventricular Tachycardia in Patients With a Ventricular Assist Device: A Systematic Review of Procedural Characteristics and Outcomes

Abstract

Objectives: This is a systematic review summarizing the procedural characteristics and outcomes of ventricular assist device (VAD)–related ventricular tachycardia (VT) ablation. Background: Drug-refractory VT refractory commonly develops post-VAD implantation. Procedural and outcome data come from small series or case reports. Methods: An electronic search was performed using major databases. Primary outcomes were VT recurrence, mortality, and cardiac transplantation. Secondary endpoints were acute procedural success and procedural complications. Results: Eighteen studies were included, with a total of 110 patients (mean age 59.6 ± 11 years, 89% men; VT storm 34%). Scar-related re-entry was ..
