Ablation index (AI)‐guided ablation according to the CLOSE protocol is very effective in terms of chronic pulmonary vein isolation (PVI). However, the optimal radiofrequency (RF) power remains controversial. Here, we thought to investigate the efficiency and safety of an AI‐guided fixed circumferential 50 W high‐power short‐duration (HPSD) PVI using the CLOSE protocol.
