Substrate-Guided Ablation of Ischemic Ventricular Tachycardia: Is it Really Necessary to Induce Ventricular Tachycardia to be Successful?

Abstract

Tolga Aksu and Kivanc Yalin

Traditionally, catheter ablation of ventricular tachycardia (VT) consists of mapping the circuit during VT, and using pacing maneuvers to localize critical isthmus of the circuit. However, substrate-guided ablation of VT is a relatively new technique and involves identifying potentially arrhythmogenic regions of myocardium in sinus rhythm and avoids the need for mapping during VT. In this short editorial article, we aimed to discuss substrate mapping of VT.
