目的探讨经导管冷冻消融与射频消融治疗房室结折返性心动过速的有效性和安全性.方法对304例房室结折返性心动过速行导管消融术病例行回顾性分析,其中冷冻组67例,射频组237例,比较两组成功率、慢径完全阻断率、房室传导阻滞率和复发率的差异.结果两组消融成功率(冷冻组98.5%与射频组97.0%,P=0.820)、慢径完全阻断率(冷冻组98.5%与射频组91.6%,P=0.088)、房室传导阻滞率(冷冻组0与射频组2.5%,P=0.413)、复发率(冷冻组0与射频组1.7%,P=0.643)差异均无统计学意义,但冷冻组慢径完全阻断率有优于射频组的趋势.结论冷冻消融治疗房室结折返性心动过速安全有效,较射频消融术有潜在优势.

Objective To compare the efficacy and safety between cryoablation (Cryo) and radiofrequency (RF) ablation for treating patients with atrioventricular nodal reentrant tachycardia (AVNRT). Methods Patients with AVNRT (n=304) were divided into Cryo group (n=67) and RF group (n=237). The procedure success rate, complete slow pathway block rate, atrioventricular block rate and relapse rate were compared between two groups. Results There was no statistically difference between 2 groups in the success rate (Cryo group 98.5% vs RF group 97.0%, P=0.820), complete slow pathway block rate (Cryo group 98.5% vs RF group 91.6%, P=0.088), atrioventricular block rate (Cryo group 0 vs RF group 2.5%, P=0.413), relapse rate (Cryo group 0 vs RF group 1.7%, P=0.643). But Cryo group had more advantage than RF group. Conclusion Efficacy and safety were comparable between cryoablation and radiofrequency ablation for treating patients with AVNRT.
