Background: The influence of deficient rims surrounding atrial septal defects (ASDs) in patients undergoing transcatheter closure has yet to be clarified. The aim of this study was to assess the influence of a deficient surrounding rim on the procedural success and clinical outcome of transcatheter ASD closure using an Amplatzer septal occluder. Methods: A total of 474 patients (mean age, 46 ± 22 years) with ostium secundum ASDs measuring ≤40 mm in diameter who had undergone attempted transcatheter closure using Amplatzer septal occluders from September 2007 to August 2013 were assessed. A comprehensive transesophageal echocardiographic examination was done to assess the morphologic characteristics of the defects in all patients. Subjects were classified into three groups by the extent and location of rim deficiency (
