摘　　要：目的 分析EnSite NavX三维标测系统指引下X线零曝光导管射频消融术治疗5例右侧显性旁道并发房室折返性性室上性心动过速的临床效果。方法 选取2014年10月—2016年7月襄阳市中心医院心内科收治的房室折返性性室上性心动过速患者5例,均经EnSite NavX三维标测系统电生理检查证实为右侧显性旁道,均在EnSite NavX三维标测系统指引下行X线零曝光导管射频消融术。结果 5例患者均成功实施X线零曝光导管射频消融术;手术时间为45~166 min;术后随访30~90 d,5例患者均未复发。结论 EnSite NavX三维标测系统指引下X线零曝光导管射频消融术治疗右侧显性旁道并发房室折返性性室上性心动过速的成功率高,可有效降低X线暴露风险。Objective To analyze the clinical effect of EnSite NavX Three - dimensional Mapping System guided radiofrequency catheter ablation without X - ray exposure in treating five right lateral accessory pathway patients complicated with atrioventricular nodal reentry - induced supraventricular tachycardia. Methods From October 2014 to July 2016 , a total of five patients with atrioventricular nodal reentry - induced supraventricular tachycardia were selected in the Department of Cardiology, the Central Hospital of Xiangyang, all of them were confirmed as right lateral accessory pathway by electrophysiological examination of EnSite NavX Three - dimensional Mapping System, and then received radiofrequency catheter ablation without X -ray exposure guided by EnSite NavX Three - dimensional Mapping System. Results All of the five patients successfully carried out the radiofrequency catheter ablation without X - ray exposure, the duration of operation was from 45 to 166 minutes; no one of the five patients occurred relapse during the 30 - to 90 - day follow - up. Conclusion EnSite NavX Three - dimensional Mapping System guided radiofrequency catheter ablation without X - ray exposure has high success rate in treating right lateral accessory pathway patients complicated with atrioventricular nodal reentry - induced supraventricular tachycardia, is helpful to reduce risk of X - ray exposure.
