摘　　要：目的:探讨经右心室流出道(right ventricular outflow tract,RVOT)射频消融(radiofrequency catheter ablation,RFCA)右前间隔显性旁道的可行性。方法:对42例右前间隔显性旁道伴房室折返性心动过速(atrioventricular reentrant tachycardia,AVRT)的患者采用RVOT标测及消融。结果:RFCA总成功率100%,随访2年无复发病例;平均X线曝光时间(15±5.4)min;无即刻及延后的P-R间期损伤。与三尖瓣环心房侧消融右前间隔显性旁道相比,总成功率高,复发率低,X线曝光时间短,损伤房室结的概率小。结论:经RVOT导管法消融治疗右前间隔显性旁道具有较高的安全性,技术上具有可行性。Objective：To investigate the feasibility of radiofrequency catheter ablation（RFCA） via right ventricular outflow tract（RVOT） in treatment of right anterior septal dominant accessory pathway.Methods：A total of 42 patients with right anterior septal dominant accessory pathway and atrioventricular reentrant tachycardia（AVRT） were mapped and ablated via RVOT.Results： The total success rate of RFCA was 100%.During a follow-up period of 2 years,no recurrence was reported.The average exposure time of X-ray was（15 ± 5.4）min,and there was no immediate and prolonged damage to the PR interval.Compared with ablation via atrial side of tricuspid annulus,the success rate was much higher via RVOT with low recurrence,shorter X-ray exposure time,and less chance of damage to the atrioventricular node.Conclusions： RFCA via RVOT can provide a more efficient and secure way in treatment of right anterior septal dominant accessory pathway.
