High-power short-duration ablation index–guided pulmonary vein isolation protocol using a single catheter

Catheter ablation for atrial fibrillation (AF) is the most commonly performed electrophysiological procedure. To improve healthcare utilization, we aimed to compare the efficacy, efficiency, and safety of a minimalistic, streamlined single catheter ablation approach using a high-power short-duration ablation index-guided protocol (HPSD) vs. a control single-catheter protocol (SP).
