Transcatheter closure of the atrial septal defect

Abstract

The atrial septal defect (ASD) is the second most common adult congenital heart disease, accounting for about 10 % of all congenital heart anomalies. Seventy percent of ASDs are of the ostium secundum type, and surgical repair is the standard of care for the other ASD types such as ostium primum and sinus venosus. Surgical correction was once the standard of care for the secundum ASD; however, over the past decades, many devices have been developed to treat the secundum ASD percutaneously. The benefits of the percutaneous approach have been well demonstrated in recent years [1, 2].
