Atrial Septal Defect (ASD): Symptoms, Causes and Treatment
An atrial septal defect (ASD) is a congenital heart defect that involves a hole in the atrial septum. This is the muscular wall that separates the two upper chambers (atria) of the heart.

ASDs and VSDs allow blood to pass from the left side of the heart to the right side. This means that oxygen-rich blood can mix with oxygen-poor blood. As a result, some oxygen-rich blood is pumped to the lungs instead of out to the body. Over the past few decades, the diagnosis and treatment of ASDs and VSDs have greatly improved.
