摘　　要：目的探讨左肺静脉共干(LCPV)与非瓣膜性阵发性房颤再次射频导管消融(RFCA)疗效的关系。方法选择2008年1月至2020年6月在绍兴市人民医院行再次RFCA的非瓣膜性阵发性房颤患者137例,其中,LCPV患者(观察组)30例,正常肺静脉患者(对照组)107例,再次RFCA术中观察肺静脉电位再连接情况,随访终点为再次RFCA 3个月后出现持续时间≥30s的房性快速性心律失常。结果再次RFCA术中发现观察组患者左肺静脉下端肺静脉电位再连接的发生率明显高于对照组(73%比38%,P<0.01)。随访期间,观察组患者再次RFCA术后心房颤动复发率较对照组低,差异有统计学意义(26.7%比56.1%,P<0.01)。结论非瓣膜性阵发性房颤LCPV患者再次RFCA后复发率较低。Objective To investigate the relation between left common pulmonary vein(LCPV)and efficacy of repeat radiofrequency ablation for non-valvular paroxysmal atrial fibrillation(PAF).Methods One hundred and thirty-seven patients with non-valvular PAF underwent repeated RFCA were enrolled in Shaoxing People's Hospital from January 2018 to June 2020.Of them,30 cases had LCPV and 107 had normal pulmonary vein.Pulmonary vein reconnection was evaluated during repeated RFCA procedure.The end point of follow-up was the occurrence of atrial tachyarrhythmia with duration≥30 seconds 3 months later after repeated RFCA.Results The incidence of pulmonary vein reconnection at the lower end of left pulmonary vein was significantly higher in patients with LCPV than in patients with normal pulmonary vein(73%vs.38%,P<0.01).During the follow-up period,the recurrence rate of PAF was significantly lower in patients with LCPV than in patients with normal pulmonary vein(26.7%vs.56.1%,P<0.01).Conclusion Recurrence rate is lower in non-valvular PAF patients with LCPV after repeated RFCA.
