Does pulsed-field ablation successfully treat epicardial PVCs from the coronary venous system after unsuccessful radiofrequency ablation?
This case report demonstrates the feasibility of using pulsed-field ablation for epicardial PVCs via the coronary venous system after failed radiofrequency ablation.
INTRODUCTION: With the entry of pulsed-field ablation (PFA) into electrophysiology, new possibilities for ablation of different substrates such as epicardial foci of premature ventricular contractions (PVCs) from coronary venous system (CVS) have been opened. METHODS: This article focuses on a case of a 27-year-old patient with frequent monomorphic PVCs of epicardial origin, treated by radiofrequency ablation, followed by PFA. RESULTS: After unsuccessful focus ablation through CVS with RFA, successful ablations from the same region with PFA were achieved. CONCLUSION: This is the first described case of successful ablation of epicardial PVCs using PFA, which we hope will help in defining indications for this novel technology and enhance quality of treatment for patients with different arrhythmias.
Meštrović et al. (Wed,) conducted a case report in Frequent monomorphic premature ventricular contractions (PVCs) of epicardial origin (n=1). Pulsed-field ablation (PFA) vs. Radiofrequency ablation (RFA) was evaluated on Successful ablation. Pulsed-field ablation successfully treated a 27-year-old patient with frequent monomorphic premature ventricular contractions of epicardial origin after unsuccessful radiofrequency ablation.
