Pediatric Atrial Septal Defect (ASD) Closure Devices

What You Need to Know

Atrial septal defect (ASD) is a type of congenital heart disease, a heart condition your child is born with. ASD means there is a hole in the septum, the wall between the heart’s upper chambers (atria). ASD occurs when the baby’s wall does not form properly during pregnancy. The heart team at Children’s National Heart Center uses the latest cardiac catheterization technology to repair these defects.


Our team is standing by to schedule your child’s appointment.
