摘　　要：目的:评估三尖瓣峡部消融对伴有典型心房扑动(房扑)和不伴典型房扑发作的心房颤动(房颤)患者术后复发的影响。方法:连续入选房颤射频消融治疗患者113例,根据有无典型房扑分为三尖瓣峡部消融组(CTI组)和未行三尖瓣峡部消融组(Non-CTI组),比较临床特征及手术特点,并随访术后典型房扑和房颤发生率。结果:Non-CTI组左房内径更大,持续性和永久性房颤的比例、左房线性消融的比例更高。而CTI组射频消融时间较Non-CTI组更长。术后典型房扑和房颤发生率2组无显著区别。结论:无典型房扑发作的房颤患者,不行三尖瓣峡部消融,不会升高术后典型房扑发生率和房颤复发率,同时射频消融时间缩短。Objective：To evaluate cavotricuspid isthmus ablation as a role in recurrence of atial fibrillation ablation with or without typical atrial flutter.Method：One hundred thirteen patients undergoing ablation for atrial fibrillation were divided CTI group which cavotricuspid isthmus（CTI） ablation were performed,Non-CTI group which CTI ablation were not performed and compared with clinical features and operational details.Follow-up consisted of incidence of typical atrial flutter and recurrence of atrial fibrillation post-operation.Result：The patients of Non-CTI group had larger left atrium and more frequently persistent or permanent atrial fibrillation and additional linear left atrial ablation performed.Total radiofrequency application times were longer in CTI group.However,incidence of typical atrial flutter and recurrence of atrial fibrillation after ablation were no significant differences in two groups.Conclusion：Avoiding CTI ablation in patients of atrial fibrillation without typical atrial flutter does not only result in a higher incidence of typical atrial flutter and recurrence of atrial fibrillation after ablation,but also a shorter radiofrequency application times.
