(FIT)-Module 6 Lectures: Special Technology Sessions-Pericardial Access for Epicardial Mapping and Ablation (Tung)

Video Transcription

Video Summary

In this presentation, Dr. Roderick Tung discusses the importance of epicardial mapping and ablation for treating ventricular tachycardia (VT), particularly focusing on non-ischemic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy (ARVC). He highlights the challenges of achieving effective ablation due to complex myocardial structures and the necessity of a two-dimensional approach to address three-dimensional cardiac issues. The lecture covers the technical aspects and considerations of epicardial access, including anatomical challenges like coronary arteries and fat, which can hinder effective ablation. Dr. Tung emphasizes avoiding epicardial procedures post-surgery due to adhesions and describes the significant role of epicardial strategies in improving treatment outcomes. He also mentions the complications associated with the procedure, such as RV puncture, and stresses careful technique using imaging guidance. The presentation concludes with key safety protocols and the evolving understanding of ventricular tachycardia mechanisms, which suggest that most VTs involve both epicardial and endocardial components. The knowledge shared aims to enhance procedure success and safety for patients.
