Characterization of Electrical Reconnection Following Pulmonary Vein Isolation Using First‐ and Second‐Generation Cryoballoon

Second‐generation cryoballoon (CB‐2) is associated with improved outcomes for pulmonary vein isolation (PVI) compared to first generation (CB‐1). However, data regarding the predictors of pulmonary vein (PV) electrical reconnection are limited. In this study, we aimed to characterize the predilection sites and predictors of reconnection in patients with recurrent atrial tachyarrhythmia (ATa) after PVI using CB‐1 and CB‐2.
