【摘要】：目的评估Carto3三维电生理标测系统导引下施行阵发性室上性心动过速(PSVT)射频消融(RFA)术的可行性、有效性及安全性。方法回顾性收集2015年3月至2016年2月接受Carto3三维电生理标测系统导引下RFA治疗的28例PSVT患者(Carto组),2014年3月至2015年2月接受X线导引下RFA治疗的36例PSVT患者(X线对照组),对比两组术中X线辐射时间、手术成功率、手术时间、并发症及复发率等差异。结果 Carto组术中X线辐射时间(2.6±2.3)min,显著低于X线组(15.8±9.5)min(P0.001),其中8例房室结折返性心动过速(AVNRT)患者零X线辐射。Carto组、X线组手术功率分别为28/28(100%)、35/36(94.4%)(P0.05),手术时间分别为(162.7±34.4)min、(149.4±46.2)min(P0.05)。Carto组无并发症发生,X线组1例AVNRT患者消融中出现一过性Ⅱ°房室传导阻滞。随访6个月,两组均无复发患者。结论 Carto3三维电生理标测系统导引下PSVT RFA安全有效,显著降低X线辐射时间,部分AVNRT患者可实现零X线辐射,不增加手术时间及手术风险。
[Abstract]:Objective to evaluate the feasibility, efficacy and safety of radiofrequency ablation of paroxysmal supraventricular tachycardia guided by Carto3 three-dimensional electrophysiological mapping system. Methods from March 2015 to February 2016, 28 patients with RFA treated with RFA guided by Carto3 three-dimensional electrophysiological mapping system and 36 patients with PSVT treated by X-ray guided RFA from March 2014 to February 2015 were collected retrospectively. X ray radiation time was compared between the two groups. The success rate, operative time, complication and recurrence rate were different. Results the operating time of X-ray radiation in Carto group was 2.6 卤2.3 minutes, which was significantly lower than that in X-ray group (15.8 卤9.5 min, P 0.001). In 8 patients with AVNRT, the power of operation was 28 / 28100 / 35 / 36 / 94.4V, respectively. The operative time was 162.7 卤34.4min and 149.4 卤149.4 卤46.2)min(P0.05).Carto, respectively, without complications in the patients with AV node reentrant tachycardia (AVNRTT). The operative power of the X-ray group was 28% 28100% 35% 3636% 94.4V P0.05, and the operative time was 162.7 卤34.4min respectively. The operation time was 162.7 卤34.4min in the patients with AV nodal reentrant tachycardia. Transient 鈪，
