This study assessed the safety of pulsed field ablation (PFA) in 17,642 patients with atrial fibrillation. No esophageal complications, pulmonary vein stenosis, or persistent phrenic palsy were reported. Major complications (0.98%) included pericardial tamponade (0.36%) and vascular events (0.30%). Stroke was rare (0.12%), and death was even rarer (0.03%). Unexpected complications included coronary arterial spasm (0.14%) and hemolysis-related acute renal failure (0.03%). The data suggest PFA has a favorable safety profile compared to conventional thermal ablation.
