“…Multiple approaches to prevent phrenic nerve injury during ablation of FAT have been described, but these approaches are generally more invasive and therefore more prone to complications, and are not easy to implement in routine daily practice. 2 , 3 , 4 , 5 The problem with conventional energy sources used for ablation of FAT, being radiofrequency or cryothermal energy, is that they are thermal and nonselective to cardiac tissue, with the risk of affecting neighboring structures. Pulsed field energy ablation (PFA) is a novel ablation modality that is currently used as an alternative energy source for pulmonary vein isolation in atrial fibrillation to overcome the potential risks and harm done by conventional thermal energy sources.…”
