目的研究Carto技术指导下的心房颤动射频消融术的疗效与安全性。方法自2008年1月~2011年6月，采用 Lasso导管、Carto标测指导下的双侧环肺静脉线性消融手术治疗42例反复发作并且药物治疗无效的阵发性心房颤动患者。通过心脏彩色多普勒超声测量左心房内径(LAD)、左心室内径(LVEDD)以及左心室射血分数(LVEF)，出院后3、6及12个月对上述三个指标进行复查。结果42例患者即刻消融成功，并发症5例：2例脑卒中，3例心包填塞。随访6个月后，7例复发房颤，手术成功率为83.33%，再次对这7例复发者进行消融手术，均成功。手术成功的患者平均心室率、 LAD、LVEDD均显著性降低（P<0.05），LVEF 显著升高（P<0.05）。结论 Carto技术指导下的射频消融术治疗阵发性心房颤动效果较为显著。

Objective To investigate the ef icacy and safety of radiofrequency ablation of paroxysmal atrial fibril ation guided by Carto. Methods Radiofrequency ablation was applied in 42 patients with drug refractory paroxysmal atrial fibril ation from January 2008 to June 2011. The LVEDD, LAD and LVEF was determined by two dimensional echocardiography, and reviewed these indicators in 3, 6 and 12 months after discharge from hospital. Results The 42 patients had ablation successful y. There were 5 complications, 2 of them were stroke, and 3 of them were cardiac tamponade. After six months fol ow-up visit, 7 of them recurrences atrial fibril ation, the success rate was 83.33%. The average ventricular rate, LVEDD, LAD and LVEF had got apparent change. The average ventricular rate, LVEDD, LAD were al had significantly reduce(P<0.05) and LVEF had significantly increased(P<0.05). Conclusion The radiofrequency ablation of paroxysmal atrial fibril ation guided by Carto was ef icacy and safety.
