超声心动图在房间隔缺损介入封堵治疗中的应用价值

The clinical value of transcatheter closure in the interventional treatment of atrial septal defect under transthoracic echocardiographic

房间隔缺损（atrial septal defect,ASD）是最常见的先天性心脏病之一,约占世界活产儿的1/1 500,是成人第2大先天性心脏病。根据其缺损的解剖学位置分为多种类型,缺损位于房间隔中央卵圆窝附近的继发孔中央型ASD最为常见,约占全部ASD的70%。

Transthoracic echocardiography can be the preferred method in the preoperative screening,intraoperative monitoring,postoperative evaluation and long-term follow-up in transcatheter closure of atrial septal defect.Retrospective analysis of 18 cases of atrial septa defect met the conditions for closure,and preoperative transthoracic echocardiography screening showed that the defects were successfully closed with no shift off.Transthoracic Doppler echocardiography were applied at 1 day and three months after operation.All occluders displayed normal position and morphology,pasted well with the surrounding tissue without swinging and loose.No residual shunt was found in the atrial level.The indicators related to the right heart before operation,including the right atrium diameter and anterior to posterior diameter of the right ventricle,pulmonary artery diameter,tricuspid regurgitation velocity and pulmonary artery systolic pressure,improved significantly compared with these indicators before operation,and the differences were statistically significant（all P〈 0.01）.
