射频消蚀术治疗房室结折返性心动过速10例

Radiofrequency current catheter ablation for 10 cases of atrioventricular nodal reentry tachycardia

作者报道以射频消蚀术(RFCA)治疗15例房室折返性心动过速(AVRT)患者的结果。其中预激综合征(WPW)6例,隐匿性旁路(CAP)9例,共15条旁路(其中左侧游离壁旁路12条,左后壁、左右间隔和右后间隔旁路各1条)。消蚀阻断14条旁路,成功率93.3％。除1例术后出现轻度主动脉瓣关闭不全外均无严重并发症,2例WPW分别于术后0.5,2月δ波复现,但无AVRT发作,其中1例再次RFCA后δ波消失。随访2～7月均无AVRT复发。

We reported the results of 17 catheter ablation procedures in 15 patients with atrioventricular reentry tachycardia (AVRT) using the radiofrequency current ablation (RFCA). Of 15 patients, 6 with Wollf-Parkinson -White syndrome (WPW) and 9 with concealed bypath tract (CAP). There were 15 accessory pathways on all patient hearts (12 left free wall, 1 left posteriolateral, 1 left posterioseptal and 1 right posterioseptal). Fourteen accessory pathways were permanently abolished and the rate of success was 93.3%. There was no serious complication except one patient had light aortic insufficience after ablation. Over a follow-up period of 2～7 (mean 4.2±2.8) months, all patients with successful ablation have been free of AVRT but on ECG of two patients, d waves reappeared 0.5 and 2 months later respectively, one of which disappeared again after another ablation procedure.
