摘要
目的 说明超声心动图在房间隔缺损封堵术中的实际应用及其重要性。方法 共有 4例继发孔型房间隔缺损患者 ,术前经胸和 /或经食道超声确定适合封堵。术中整个操作过程包括球囊测径到置入相应型号的封堵器 ,均在超声心动图和X线引导下进行。结果 术后即刻超声检查显示完全封堵 ,无残余分流。随访 10～ 14月 ,封堵器位置固定 ,右心负荷减轻 ,无并发症出现。结论 经导管封堵房间隔缺损成功率高 ,操作简便 ,创伤小 。
Objective To explain the clinical application and importance of echocardiography in the transcatheter occlusion of atrial septal defect(ASD) Methods Four patients were assessed by transthoracic and/or transesophageal echocardiography as ostium secundum defect(OSD)with size,position and rims suitable for occlusion The procedure ,from ballon sizing of stretched diameter to device development,was guided by echocardiography and fluoroscopy Results Immediate assessment by echocardiography showed complete occlusion and no residual shunt in all four After follow-up of 10～14months,the device remains in proper place,overload of right ventricles has diminished and not a complication has occurred Conclusion The transcatheter occlusion of ASD in which echocardiographic guidance plays an important role,is easy ,effective and much less invasive
