What are the symptoms of an ASD?

Many people have no idea they have an ASD because they do not have symptoms. Some patients find out about the defect when a chest X-ray for another problem shows that the right side of the heart is bigger than normal.

By age 50, an ASD can cause symptoms like shortness of breath, fainting, irregular heart rhythms or fatigue after mild activity or exercise.
