Abstract:
Objective To explore the clinical value of real-time three-dimensional echocardiography (RT-3DE) in percutaneous transcatheter closure treatment of atrial septal defect (ASD). Methods The sizes,shapes and sites of ASD were visualized by RT-3DE and measured by full volume rendered three-dimensional echocardiography (3DE) before operation and after closure operation in 11 ASD patients,and compared with those from two-dimensional echocardiography(2DE) and the operation. Results Before the operation,RT-3DE visualization showed that the secundum ASD′s sites of the 11 patients were central and shapes were mostly ellipse. In this study a significant difference was found in the measurements of long distances of ASD between 3DE and 2DE [( 28.9 ? 8.2 )mm vs ( 20.0 ? 7.3 )mm,P 0.05 ]. Maximal diameters of defects measured by 2DE[( 21.1 ? 3.5 )mm,P
