Atrial septal defect (ASD) is a congenital (present at birth) heart defect sometimes called “hole in the heart.” The hole is in the wall between the upper two heart chambers. If your child has an ASD, our pediatric heart care team in the Nemours Children's Cardiac Center will address your concerns, answer your questions, and provide the latest in proven treatment options. Our board-certified, fellowship-trained pediatric cardiologists and cardiothoracic surgeons (specialists in surgical procedures of the chest, including heart and lungs) deliver top-notch care for your child.
