atrial septal defect repair

Full Definition

Atrial septal defect (ASD) repair involves surgical closure of abnormal communications between the right and left atria, most commonly secundum, primum, or sinus venosus defects. The repair technique depends on defect size and location: small defects may be closed primarily with sutures, while larger defects typically require patch closure using autologous pericardium or synthetic material. The surgery is usually performed through a median sternotomy using cardiopulmonary bypass.

Usage

Usage note: Specify ASD type (secundum, primum, sinus venosus) and repair method (primary vs. patch).
