About this episode

The episode discusses empirical evidence supporting anatomical ablation strategies for 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 Authors Takumi Yamada and G. Neal Kay Podcast Contributors Dr. Deep Chandh Raja, MBBS, MD, PhD Dr. Chi Keong Ching, MBBS, FHRS Dr. Haris M. Haqqani, MD, PhD, FHRS Host and…
