Reddy et  al (Am Coll Cardiol 2019;74:315, PMID 31085321) evaluated whether pulse field ablation (PFA) allows durable pulmonary vein (PV) isolation without damage to collateral structures. Two trials assessed the safety and effectiveness of catheter-based PFA in paroxysmal atrial fibrillation. Invasive elec trophysiological mapping was repeated after 3 months to assess the durability of PV isolation. In 81 patients, all PVs were acutely isolated by monophasic (n = 15) or biphasic (n = 66) PFA with ≤3 minutes elapsed delivery per patient, a skin-to-skin procedure time of 92.2 ± 27.4 minutes, and a fl uoroscopy time of 13.1 ± 7.6 minutes.
