Abstract

Background: Since the Amplatzer Septal Occluder ASO was approved in Japan on March 2005, more than 1000 procedures have been attempted as of July 2009. Meanwhile severe complications had occurred, including 2 erosion cases and 6 migrations. Methods: To investigate the efficacy and the safety of percutaneous ASD closure, 115 cases of ASD closure with the ASO device between August 2006 and July 2009 were compared with 55 surgical closure cases retrospectively.
