For treatment of atrial fibrillation (AF), pulmonary vein isolation (PVI) by cryoballoon (CB) ablation1 is an effective and safe technique with many potential advantages over radiofrequency (RF) ablation.2 The second‐generation CB (CB‐Adv, Medtronic, Minneapolis, MN, USA) is effective for acute PVI and shows good clinical outcomes.3 RF and CB‐Adv PVI reportedly show comparable outcomes among persistent AF patients, as indicated by one study conducted without contact force (CF)‐sensing catheters4 and another with only a 1‐year follow‐up.5 Here, we compared arrhythmia recurrence rates for CB‐Adv and RF catheters with a longer follow‐up period, including CF‐sensing catheters, among persistent AF patients with left atrial (LA) enlargement, some of whom received roof lines (RLs) plus PVI.
