Percutaneous device closure for secundum-type atrial septal defect: short and intermediate-term results.

Background: Device closure of an isolated secundum type atrial septal defect (ASD) has been used as an alternative method for open surgical closure with comparable success and lower morbidity. In this study we evaluated the procedural success and mid-term follow-up results of percutaneous closure of secundum ASD with an Amplatzer™Septal Occluder(ASO) device or a Figula ASD occluder device.

Methods: From June 2001 to January 2009, 74 consecutive patients were scheduled for percutaneous device closure in two centers in Tehran, Iran.
