Impact of a Chronic Total Occlusion in an Infarct‐Related Artery on the Long‐Term Outcome of Ventricular Tachycardia Ablation

Abstract

IRA-CTO is an independent predictor of VT recurrence after ablation and identifies a subgroup of patients with high recurrence rate despite a successful procedure. IRA-CTO is associated with greater scars and border zone area; however, this association does not completely justify its proarrhythmic effect.
