The Lead Episode 143: A Discussion of The Empirical Evidence in the Successful Anatomical Ablation of Idiopathic LV Summit Ventricular Arrhythmias

In this discussion, Dr. Deep Chandh Raja, MBBS, MD, PhD, is joined by Dr. Chi Keong Ching, MBBS, FHRS, and Dr. Haris M. Haqqani, MD, PhD, FHRS, to review the growing empirical evidence supporting anatomically guided ablation strategies for idiopathic left ventricular (LV) summit ventricular arrhythmias. The panel highlights how integrating multimodality mapping with a nuanced understanding of the region's complex anatomy can improve procedural success and safety. They also emphasize the role of evolving techniques and shared clinical experience in refining outcomes for these challenging cases.   Learning Objectives Describe the anatomical challenges of the left ventricular (LV) summit and their implications for catheter ablation of idiopathic ventricular arrhythmias. Evaluate the role of multimodality mapping and anatomically guided strategies in improving procedural success and safety.  Identify emerging techniques and clinical insights that inform optimal ablation approaches for LV summit arrhythmias.    Article AuthorsTakumi Yamada and G.
