Abstract
Purpose
This study was designed to evaluate the efficacy and safety of transcatheter closure of large atrial septal defects (ASD).
Methods
Eighteen patients diagnosed as ostium secundum defect with a diameter of 30‐40 mm were enrolled in this study. With the guidance of echocardiography and fluoroscopy, the Amplazter occlusion devices were implanted percutaneously through the femoral vein.
Results
A small residual left‐to‐right shunt was detected with echocardiography immediately postprocedure but resolved after 1 week. The occlusion devices remained in proper position, and there was no residual shunt at 1‐ and 29‐month follow‐ups. Cardiac function and atrial sizes improved significantly as compared with the preclosure states.
Conclusions
Transcatheter closure of large atrial septal defects with the Amplazter occlusion device is feasible, safe and effective. Copyright © 2008 Wiley Periodicals, Inc.
