What's an Atrial Septal Defect (ASD)?
An atrial septal defect (ASD) — sometimes called a hole in the heart — is a heart defect some babies are born with. There's an abnormal opening in the dividing wall between the upper filling chambers of the heart (the atria).
Most ASDs are diagnosed and treated successfully with few or no problems.
