Acute coronary artery occlusion and ischemia-related ventricular tachycardia during catheter ablation in the right ventricular outflow tract

J Cardiovasc Electrophysiol. 2021 Feb;32(2):547-550. doi: 10.1111/jce.14809. Epub 2020 Nov 18.

Abstract

Coronary artery injury is a rare complication of catheter ablation in the right ventricular outflow tract (RVOT). Furthermore, acute myocardial ischemia usually causes polymorphic ventricular tachycardia (VT) or ventricular fibrillation. We herein describe a case in which catheter ablation for VT originating from the RVOT provoked ischemia-related VTs due to acute occlusion of the left anterior descending artery.

Keywords: catheter ablation; coronary artery; left anterior descending artery; right ventricular outflow tract; ventricular tachycardia.
