Transthoracic echocardiographic guidance for closure of atrial septal defects with amplatzer occlusion device / 中国介入心脏病学杂志

ABSTRACT

Objective To evaluate transthoracic echocardiographic guidance for closure of atrial septal defects with Amplatzer occlusion device in the adults Methods Thirty patients with atrial septal defects were occluded by use of Amplatzer septal occluder The mean age was (32 3?14 7) years (ranging from 13-65 years) Transthoracic echocardiography was undertaken for guidance for closure before and in the procedure of intervention Transthoracic echocardiography was done immediately, one month and three month respectively after intervention to evaluate the treatment efficiency Results Twenty four patients were treated successfully directly by guidance of transthoracic echocardiography during the period of closure, the total effectiveness was 80%. Five patients needed to have transesophageal echocardiography before closure to select indication and another one patient was treated successfully by adding transesophageal echocardiography for guidance in the procedure There was no significant complication that occurred during the procedures, and there was no emergency surgical case Trivial to small residual shunts were found in 2 cases (6 7%) immediately after the procedure No residual shunts were found in the one month follow up, and all patients had no displacement and recanalization in the one month follow up Conclusion Transthoracic echocardiography can guide most of atrial septal defect patients for closure of atrial septal defects with the Amplatzer occlusion device
