摘　　要：目的评价导管射频消融术治疗特发性房颤的临床疗效和安全性。方法38例房颤患者接受治疗，其中阵发性房颤29例，持续性房颤9例。6例行肺静脉电隔离术，32例行Carto指导下环肺静脉前庭隔离术，消融终点均为双侧肺静脉完全电隔离。结果38例患者术后即刻均成功达到消融终点，手术过程中无并发症发生。术后3～5d有8例出现了房性心律失常。2例复发患者中1例为持续性房颤转为阵发性房颤，再次行导管消融获得成功；1例阵发性房颤发作频率明显减少、口服胺碘酮可维持窦性心律。其余36例患者均无房颤复发。所有患者术后均未发生与导管消融有关的并发症。结论导管射频消融术治疗特发性房颤是安全有效的治疗方法。Objective To investigate the effect and safety of catheter ablation for idiopathic atrial fihrillation（AF）. Methods Thirty eight cases were included in this study,with 29 cases of paroxysmal AF,and 9 cases of persistent AF. Pulmonary vein isolation （PVI） was performed in earlier 6 cases. Eleetroanatomical systems （Carto） guided circumferential puhnonary veins antrum ablation was performed in 32 cases. The endpoint of ablation was complete electro isolation of pulmonary veins. Results Thirty-eight cases were successfully achieved the endpoint after the ablation instantly. No severe complication was found during the procedure. Eight cases developed atrial arrhythmias at 5-8d after ablation. Two patients were early recurrence,one patient with persistent AF was converted to paroxysmal and underwent re-ablation succussfully, the other with paroxysmal AF decreased episode frequency and took amiodarone. Other 36 cases were not recurrence. No complication was found during the follow-up. Conclusion Catheter ablation is safe and effective for treating idiopathic AF.
