经胸超声心动图监测下用Amplatzer封堵器治疗房间隔缺损

目的：评价在经胸超声心动图(TTE)监测下用Amplatzer封堵器介入治疗房间隔缺损(ASD)的可行性及实用价值。方法：全组共18例继发孔型ASD患者，均在常规C型臂X线机透视和TTE指导下经导管置入Amplatzer封堵器。结果：18例患者中有2例未放置成功而改为开胸手术；16例均成功置入Amplatzer封堵器，即刻完全堵闭，术后随访3个月至2年，TTE示ASD仍被完全封闭，未见残余分流。随访期间无任何并发症。结论：在TTE和X线透视指导下用Amplatzer封堵器治疗继发孔型ASD安全可行，具有一定实用价值。

Transcatheter closure of secundum atrial septal defect using Amplatzer septal device under transthoracic echocar-diography guidance

Objective: To evaluate the feasibility and utility of transcatheter closure of secundum atrial septal defect using Amplatzer occluder under transthoracic echocardiography(TTE) guidance. Methods: 18 patients with secundum atrial septal defect (ASD) were diagnosed. The Amplatzer occluder was used for transcatheter closure of secundum atrial septal defect under TTE and X-ray guidance for all the patients. Results: The Amplatzer occluder was deployed correctly in all patients except two patients who underwent cardiac operation. There were complete closures in 16 patients immediately. 16 patients were followed up from 3 months to 2 years after operation, the closure of ASD was still complete in all patients.no residual shunt or any other complications occurred. Conclusions: Amplatzer occluder is an efficient and safe nonsurgical method for closure of secundum atrial septal defect under TTE and X-ray guidance.
