【摘要】 目的评价磁导航技术应用于室上性心律失常消融治疗的远期效果。方法将经过心内电生理检查确诊的室上性心动过速患者随机分为两组各40例。A组采用常规技术和4 mm温控导管消融;B组采用磁导航系统和温控磁大头导管消融。通过出院后随访的形式比较两组患者的成功率、并发症和复发率。结果两组患者全部一次消融成功,无并发症,随访(24.0±5.0)个月,A组、B组患者均无心动过速复发。结论采用磁导航技术能安全有效地实施遥控标测和消融治疗,无并发症,远期效果好。更多还原

【Abstract】 Objective To assess the long-dated effect of remote magnetic navigation for mapping and ablating supraventricular arrhythmia. Methods Patients with supraventricular arrhythmia diagnosed by electrophysiological ex-amination were randomized into two groups. Forty patients were enrolled to each group respectively. Conventional 4mm tip temperature controlled ablation catheter was used in routine technique procedure(RTP) group and magnetic navi-gated temperature controlled ablation catheter was used in MNS group. Following parameters were obtained and between the two groups:success rate,complication rate and recurrence rate by follow-up. Results The procedures were successful in all patients.and no complication was reported. No tachycardia in group A and group B recurred during(24.0±5.0) months follow-up. Conclusion Remote control mapping and ablation of supraventricular tachyarrhythmia is safe and feasible using magnetic navigation technique. This technique can also not increase complication rate and recurrence rate of patients. The long-dated effect of remote magnetic navigation for mapping and ablating supraventricu-lar arrhythmia.is good.更多还原
