目的评价经导管置入Amplatzer封堵器治疗继发孔型心房间隔缺损(ASD)的疗效。方法 11例患者中男3例，女8例，年龄4～46岁(平均25岁)。术前经多普勒超声心动图检查房间隔缺损直径为12～28mm，平均(18.5±6.1)mm。在透视及经超声心动图引导下经导管置入Amplatzer封堵器闭合ASD。结果 11例ASD直径的球囊测量值为(25.2±8.3)mm(15～36mm)，选择的封堵器直径为(25.4±7.7)mm(15～36mm)。11例封堵器置入均获得成功，术中无并发症。2例术后即刻超声检查显示微量残余分流。术后1周复查均无分流。结论经导管置入Amplatzer封堵器治疗ASD是一种有效的非手术方法。

Objective　To evaluate the efficiency of transcatheter occlusion of secundum atrial septal defect (ASD) using Amplatzer occluder. Methods　There were 11 patients (3 male, and 8 female, mean age 25.3±14.00 years), ranging from 4 to 46 years. Echocardiography confirmed the ASD with a diameter of 18.51±6.10 mm (ranging from 6 to 28mm). All patients with ASD were treated with using the Amplatzer occluder under guidance of fluorscopy and Echocardiography through percutaneous approach. Results　The mean balloon stretched diameter of the ASDs in 11 patients was 25.20±8.30mm(15～36mm). The mean diameter of the occluder selected was 25.40±7.71mm(15～36mm). The successful rate of placement of the Amplatzer occluder was 100%. No complication was found during the procedures and the followo-up. Trivial residual shunt was found in 2 patients immediately after the procedures, and there was no residual shunt 1 week after the procedures and during follow-up. Conclusions　Transcatheter closure of secundum ASD using the amplatzer septal occluder is an efficient nonsurgical method.
