射频消融术治疗室上性心动过速1000例的疗效

Radiofrequency Current Ablation for Supraventricular Tachycardia: A Clinical Report of 1?000 Patients

目的评价射频消融术治疗阵发性室上性心动过速的安全性和有效性。 方法 10 0 0例阵发性室上性心动过速的患者接受射频消融术 ,术后平均随访 2 5± 19月 (1～ 110月 )。 结果射频消融术治疗室上性心动过速的总成功率为 98.9% (989/ 10 0 0 ) ,其中旁道参与的心动速度 5 90例 (5 98条旁道 ) ,阻断 5 88条 ,成功率 98.3% ;房室结折返性心动过速 4 10例 ,慢径消融成功率为 99.8%。 14例 (1.4 % )患者出现并发症。随访期间 ,16例 (1.6 % )患者复发 ,再次接受射频消融术均获成功。 结论射频消融术是目前治疗阵发性室上性心动过速最为有效的手段 ,其成功率高 ,并发症少 。

Objective To evaluate the efficacy and safety of radiofrequency current ablation for paroxysmal supraventricular tachycardia(PSVT). Methods Radiofrequency current ablation(RFCA) was performed in 1?000 patients with paroxysmal supraventricular tachycardia. The average duration of follow-up was 25±19(range 1 ～ 110 months). Results All patients were treated by radiofrequency current ablation with a total success rate of 98.9%. Among 590 patients with paroxysmal supraventricular tachycardia caused by atrioventricular accessory pathways, 588 atrioventricular accessory pathways were successfully ablated with a success rate of 98.3%(588/598). In 410 patients with atrioventricular nodal reentrant tachycardia, the slow pathways were successfully abolished in 409 patients with a success rate of 99.8%. Complications occurred in 14 patients(1.4%). During follow-up, PSVT recurred in 16 patients(1.6%) and was permanently eliminated by reapplication of RFCA. Conclusion RFCA is a highly valuable non-drug therapy for PSVT with a high success rate, few complications, and low recurrence.
