背景- 使用冷冻球囊或射频消融进行肺静脉（PV）隔离是抗心律失常药物难治性症状性阵发性房颤（AF）的基础疗法。三分之一的患者复发，主要是由于PV重新连接。- 描述既往接受过射频消融或冷冻球囊消融的患者中重新连接部位的不同位置，并比较两种情况下重做手术的特征。- 收集人口统计学数据和初始消融（冷冻球囊或射频）的特征。回顾了再传导间隙的数量和位置以及重做特征。- 纳入了74例计划再次消融阵发性房颤的患者; 38例在首次手术期间接受了射频消融治疗，36例接受了冷冻球囊消融治疗。对于初始消融，冷冻球囊消融的手术和透视时间明显更短（147.8 ± 52.6 min vs. 226.6 ± 64.3 min [P
Background. - Pulmonary vein (PV) isolation, using cryoballoon or radiofrequency ablation, is the cornerstone therapy for symptomatic paroxysmal atrial fibrillation (AF) refractory to antiarrhythmic drugs. One-third of the patients have recurrences, mainly due to PV reconnections.Aims. - To describe the different locations of reconnection sites in patients who had previously undergone radiofrequency or cryoballoon ablation, and to compare the characteristics of the redo procedures in both instances.Methods. - Demographic data and characteristics of the initial ablation (cryoballoon or radiofrequency) were collected. Number and localization of reconduction gaps, and redo characteristics were reviewed.Results. - Seventy-four patients scheduled for a redo ablation of paroxysmal AF were included; 38 had been treated by radiofrequency ablation and 36 by cryoballoon ablation during the first procedure. For the initial ablation, procedural and fluoroscopy times were significantly shorter for cryoballoon ablation (147.8 +/- 52.6 min vs. 226.6 +/- 64.3 min [P
