Redo ablation after primary radiofrequency or pulsed field ablation for paroxysmal or persistent atrial fibrillation: results from a pre-specified substudy of the BEAT-AF trial
Pulmonary vein isolation (PVI) remains the cornerstone of interventional therapy for atrial fibrillation (AF). The introduction of pulsed field ablation (PFA) has further advance PVI techniques. This novel energy modality has demonstrated comparable efficacy and improved safety profile compared with radiofrequenc...
