摘　　要：目的探讨EnSite NavX^(TM)系统指引下X线零曝光经导管射频消融治疗典型心房扑动的可行性和安全性。方法纳入2013年9月至2016年6月在襄阳市中心医院接受经导管射频消融治疗的典型心房扑动患者18例。18例患者经超声心动图检查均无心脏血管结构异常。所有患者均在EnSite NavX^(TM)系统指引下实施X线零曝光电生理检查和经导管射频消融治疗。观察射频消融后三尖瓣达到双向阻滞及补充的射频消融次数、手术时间、术中及术后近期并发症情况、术后30~90 d心房扑动复发情况。结果所有患者经导管射频消融均成功,其中10例(10/18)为沿设计消融线一次射频消融后即达到双向阻滞,5例(5/18)第二次补点消融达到双向阻滞,3例(3/18)第三次补点消融达到双向阻滞。手术时间为(118.36±42.25)min,未发生射频消融相关并发症,随访30~90 d无复发。结论 EnSite NavX^(TM)系统引导下X线零曝光经导管射频消融治疗典型心房扑动安全可行。Objective To explore the feasibility and safety of zero-fluoroscopic catheter navigation for radiofrequency catheter ablation of typical atrial flutter guided by the Ensite NavX^TM system. Methods Non-fluoroscopic radiofrequency catheter ablation navigated by the Ensite NavX^TM system was performed in 18 patients with typical atrial flutter and normal cardiac structure admitted from September 2013 to June 2016. Results The success rate of procedure was 100%. The total fluoroscopic exposure time was zero minute for every case. The average procedure time was （ 118.36 ± 42. 25 ） minutes, and no complications occurred. No arrhythmia reoccured in 30 - 90 days of follow-up. Conclusions Radiofrequency catheter ablation of typical atrial flutter may be safely and effectively guided by the Ensite NavX^TM system and without X-ray exposure.
