Left Ventricular Summit Arrhythmias: State-of-the-Art Review of Anatomy, Mapping, and Ablation Strategies

JACC Clin Electrophysiol. 2024 Nov;10(11):2516-2539. doi: 10.1016/j.jacep.2024.09.008. Epub 2024 Oct 30.

Abstract

The left ventricular summit (LVS) is the most common site of epicardial arrhythmias. Ablation of LVS arrhythmias continue to pose a challenge to the electrophysiologist because of its complex and intimate anatomical location. In this review, we undertake a detailed examination of the intricate anatomy of the LVS alongside a comprehensive synthesis of mapping and ablation strategies used to treat LVS arrhythmias.

Keywords: ablation; left ventricular summit; mapping; ventricular arrhythmia; ventricular premature complexes; ventricular tachycardia.
