118例右侧房室旁道导管射频消融治疗分析

Analysis of radiofrequency catheter ablation used in patients with arrhythmiogenic right atrioventricular accessory pathway

目的 分析右侧房室旁道电生理特性及导管射频消融 (RFCA)术操作要点 ,试图总结实用有效的常规消融方法。方法 利用RFCA技术阻断右侧房室旁道参与的折返性心动过速 118例 ,其中显性旁道 71例 ,隐匿性 47例。结果 首次消融成功率 89 0 % ,随访 1个月～ 3年 ,15例( 12 7% )复发 ,经再次RFCA14例成功。最终治愈 113例 ,治愈率 95 8% ,无严重并发症发生。

Objective 118 cases of right atrioventricular accessory pathways (Aps) treated by radiofrequency catheter ablation (RFCA) were analyzed retrospectively for a practical and effective ablation procedure.Methods 118 patients with right atrioventricular APs were treated by RFCA. 71 of them manifested APs and 47 had concealed APs.Results 89 0% of the patients were successfully treated with catheter ablation in the first time.During the follow up of 3 months to 3 years,14 of the 15 cases,which had recurrences of conduction prbolems (recurrence rate 12 7%),were successfully treated with catheter ablation.Conclusion The precise APs mapping and the catheter stability are two keys to success.
