Atrial Septal Defect: Treatment
Pronounced: AY-tree-uhl SEP-tull DEE-fectEn Español (Spanish Version)
The atria are the the upper chambers of the heart. An atrial septal defect (ASD) is a hole in the wall between the left and right chambers of the atria. It is present at birth.
Blood passes from the left atrium to the right atrium in babies born with ASD. This eventually can cause problems in the lungs.
