Percutaneous closure of atrial septal defects has evolved since 1975, leading to various device designs including the Amplatzer Septal Occluder.
A commentary discussing the evolution and potential complications of percutaneous atrial septal defect closure devices.
Percutaneous closure of atrial septal defects (ASDs) was pioneered by King and colleagues using a device made from 2 interlocking umbrellas in 1975.1 Since then, an intensive research and development effort has resulted in a wide range of ASD closure device designs. The Amplatzer Septal Occluder (Abbott. Abbott Park, Ill) is a self-expanding and self-centering nitinol mesh device that was introduced in 1995.2 This device consists of 2 discs connected by a waist that sits in the ASD.
