What Is an Atrial Septal Defect Repair?
An atrial septal defect repair is a surgical procedure that aims to correct a congenital heart defect called an atrial septal defect (ASD). Infants born with ASD have a defect within the atrial septum — the wall that divides and separates the uppermost chambers of the heart. This wall usually closes during fetal development. Babies with ASD have an opening in the wall that allows oxygenated blood to pass from the left atrium into the right atrium. This disorder limits the amount of oxygen-rich blood that can be supplied from the heart to the rest of the body.
