S-JS13. LAHRS/HRS Joint Session: Catheter Ablation of Atrial Fibrillation: Is the Epicardium the Key to Improve the Results?

Session Description: The importance of the myofiber architecture to explain arrhythmogenesis was early proposed and catheter ablation techniques for AF have been in part developed based on this knowledge. However, the procedure still fails in a significant proportion of patients whose mechanisms are not completely understood. New clinical evidence and imaging methodologies have suggested a role of epicardial bundles to explain failed procedures. Detailed understanding of the endo-epi distribution of myocardial fibers and its correlation with clinical observations could help to design new approaches to improve the results of catheter ablation for AF.
