三维标测系统指导下阵发性心房颤动导管射频消融近期疗效分析

Short-term effect analysis of the catheter ablation guided by CARTO system in patients with paroxysmal atrial fibrillation

目的：评价三维标测系统（CARTO）指导下心房颤动导管射频消融治疗的疗效和安全性。方法：2006年3月至2009年3月期间住院治疗的阵发性房颤患者32例，男性22例，女性10例，年龄38—71（61±6．9）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隔离，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：32例患者均实现肺静脉电隔离，在术后至少3个月的随访中，6例复发，单次消融成功率为81．25％。6例复发患者中2例接受再次消融并成功，两次消融成功率为87．5％。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。

Objective： To investigate the safety and efficacy of circumferential pulmonary vein linear ablation guided by 3-D mapping system （CARTO） in patients with atrial fibrillation. Methods： From March 2006 to March 2009 thirty two patients[22 male and 10 famale,mean age was（61 ＋6.9） years] with paroxysmal atrial fibrillation underwent circumferential pulmonary vein linear ablation guided by 3-D mapping system（ CARTO system）, the end point was PV isolation. Every case received oral antieoagul ant（warfarin） and antiarrhythmic drugs for 3 months. ECG and Hoher were applied 1,3,6 months after ablation. Results： All the 32 patients attained the ablation endpoint. After a follow-up of 3 months at least, atrial fibrillation recurred in 6 cases, the first clinical success rate was 81.25%. Two case underwent re-ablation and PV isolation was achieved, the total clinical success rate was 87.5 %. Conclusion ： Circumferential pulmonary vein linear ablation guided by 3-D mapping system（ CARTO system） was safe and effective for paroxysmal atrial fibrillation therapy.
