【摘要】 目的评价三维标测系统(CARTO,ENSITE3000)指导下心房颤动导管射频消融治疗的近期疗效和安全性。方法阵发性心房颤动患者38例,男性22例,女性16例,年龄32～75(63±12)岁。在三维标测系统指导下行环肺静脉线性消融,消融的主要终点为肺静脉电位消失,术后口服华法林及抗心律失常药物3个月,术后1,3,6个月复查心电图及24小时动态心电图。结果 38例患者均实现环肺静脉电隔离,在术后至少3个月的随访中,6例复发,单次消融成功率为84.21%。6例复发患者中接受药物治疗6个月,有3例仍有发作。结论三维标测系统指引导管环肺静脉线性消融治疗阵发性心房颤动疗效高,安全性好。更多还原

【Abstract】 Objective To investigate the safety and efficacy of circumferential pulmonary vein linear ablation guided by 3-D mapping system(CARTO,ENSITE3000) in patients with paroxysmal atrial fibrillation.Methods 38 patients [22 male and 16 famale,mean age was(63±12) years] with paroxysmal atrial fibrillation underwent circumferential pulmonary vein linear ablation guided by 3-D mapping system(CARTO or ENSITE3000 system),the end point was PV isolation.Every case received oral anticoagu1ant(warfarin) and antiarrhythmic drugs for 3 months after operation.ECG and Holter were applied 1,3,6 months after ablation.Results All the 38 patients attained the ablation endpoint.After a follow-up of 6 months at least,atrial fibrillation recurred in 3 cases,the first clinical success rate was 81.25%.Three case underwent re-ablation and PV isolation was achieved,the total clinical success rate was 84.21%.Conclusion Circumferential pulmonary vein linear ablation guided by 3-D mapping system(CARTO or ENSITE3000 system) was safe and effective for paroxysmal atrial fibrillation therapy.更多还原
