心脏直视瓣膜置换术中同期双极射频消融治疗心房颤动

Bipolar Radiofrequency Maze Operation For Atrial Fibrillaton During Concomitant Cardiac Valve Replacement Surgery

目的:探讨心脏手术同期施行双极射频迷宫手术治疗心房颤动(AF)的安全性及效果。方法:在心脏瓣膜手术同期施行双极射频迷宫手术10例入治疗组,同期随机的10例瓣膜置换术合并房颤患者入对照组,回顾性分析和随访,比较两组术后住院时间、机械通气时间、CPB(体外循环)时间、超声心动图等各项指标,评价射频消融手术的安全性及效果。结果:全组病例无死亡,超声显示左心房比术前明显缩小,治疗组术后1、3、6个月窦性心律分别为80.0%、90.0%、80.0%,对照组分别为10.0%、10.0%、0%。结论:心脏直视手术同期施行双极射频迷宫手术治疗AF安全有效。

Objective：The purpose of this study was to examine the safety and effectiveness of bipolar radiofrequency maze operation for atrial fibrillation（AF） undergoing cardiac valve replacement surgery.Methods： Twenty patients combined AF with rheumatic valve disease needed to have cardiac valve replacement surgery in last few years were randomly divided into Ablation group and Control group（10 in each group）,and basical conditions in two groups were comparative.In Ablation group,both COX IV radiofrequency ablation and artificial mechanical valve replacement were done.In Control group,the artificial mechanical valve replacement were made alone.the basical conditions were compared for both groups.Collect the datas of the time of postoperative hospital stay,mechanical ventilation time,CPB time and Echocardiographic indicators.Analyse the postoperative complications to evaluate the security.Get the follow-up in both group to evaluate the validity.Results： No one died in the Alation group,there was a significant decrease in left atrial dimension.The stable rate of sinus rhythm on the 1 month,3months,6months after operations in Ablation group are 80.0%,90.0%,8 0.0%and 10.0%,10.0%,0%in Control group.Conclusion： Bipolar radiofrequancy maze operation is an effective surgical option for treating AF.
