Percutaneous closure of atrial septal defects: immediate and mid-term results.

Introduction: The incidence of percutaneous closure of secundum atrial septal defects (ASD) and patent foramen ovale (PFO), which has become an established therapy, is constantly increasing. In this study, which is the first in the Greek literature, we present the immediate and mid-term results from this intervention in our center.

Methods: From April 2004 to April 2008, 103 patients underwent percutaneous closure of an ASD or PFO using Amplatzer closure devices.
