Abstract
Catheter ablation (CA) has been commonly used in treatment of symptomatic patients with Atrial Fibrillation (AF) with Pulmonary vein isolation (PVI) being considered as the cornerstone of AF ablation procedure (1). However, there are major challenges facing PVI using current CA technologies including the durability of PVI, risk of Pulmonary veins (PV) reconnection, collateral damage especially phrenic nerve injury and oesopahguial injury (2). Therefore, better technology was needed to improve efficacy and safety. Pulsed field ablation (PFA) has emerged over last few years as new ablation modality for the treatment of AF using non-thermal energy and irreversible electroporation. This review provides an update on concept, current evidence, gap in evidence and available technology for PFA of AF.
