1 Introduction Catheter ablation is an established treatment for atrial fibrillation (AF), with increasing global uptake. Traditionally, thermal energy sources such as radiofrequency (RF) and cryoballoon (CB) have been used to achieve pulmonary vein isolation (PVI), the cornerstone of AF ablation [1, 2]. More recently, pulsed-field ablation (PFA), a non-thermal modality that selectively targets myocardial cells through electroporation, has emerged as a promising alternative [3-6].
