title: Effect on right ventricular volume of percutaneous Amplatzer closure of atrial septal defect in adults.
abstract: In adult patients with atrial septal defects (ASDs), right ventricular (RV) cavity size may return to normal after operative closure. This study demonstrated improved RV volumes and right atrial areas in 20 adult patients after successful transcatheter closure of large ASDs. RV volumes decreased by 22%, 30%, and 41% at 1 day, 1 month, and 6 months, respectively, after the procedure. Right atrial areas decreased by 5%, 23%, and 26%, respectively, over the same time.
