Long-term follow up of interventional therapy of secundum atrial septal defect.

Background: The percutaneous transcatheter closure of secundum atrial septal defect (ASD) is increasingly a widespread alternative to surgical closure. The aim of this study was to assess long-term results of percutaneous closure of secundum-type atrial septal defect (ASDII).

Methods: Between January 2001 and December 2005, 61 patients underwent a successful percutaneous closure of ASDII; including 25 male and 36 female.
