Echocardiographic guidance of transcatheter closure of vent ricular septal defects using the Amplatzer device / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the applied values of echocadiography in closing membranous ventricular septal defects (VSD) with the Amplatzer devices. Methods The VSD were closed by transcatheter Amplatzer closure devices in nine patients. The patients′ age ranged between 15-45 years old,mean (26?10) years old. The VSD diameter was measured from 3 to 15 mm. Seven patients were guided by transthoracic echocardiography and 2 patients by transesophageal echocardiography. Results All VSD were successfully closed by the Amplatzer devices, without complications. The device size ranged from 6 to 18 mm. No residual shunt and complication were detected by the echocadiography in intraoperation and 3 or 4 days after operation. Conclusions Echocardiography plays an important role in closing VSD with Amplatzer device, not only in intraoperative guidance and monitor, but also in post-operative follow up study.
