This occurs when babies are born with a hole in the wall between the heart’s two upper chambers. In severe cases, it can lead to pulmonary hypertension, irregular heart rhythms and stroke.

The aortic valve, which controls blood flow from the heart to the aorta, has two valves instead of three. It can cause abnormal blood flow and enlargement of the aorta.

The left side of the heart doesn’t form correctly, hampering its ability to pump blood. This often leads to the need for a Fontan procedure and single ventricle physiology.

An abnormally small portion of the aorta does not allow blood to get to the lower body. This often requires surgery or stent placement.

This occurs when there is a hole in the heart as well as a problem with the pulmonary valve. Some babies get surgery early in life and others can wait a few months.

This is one of the most common congenital heart defects that often requires valve replacement.

When the origins of the two large arteries in the chest are reversed, different treatment types are offered but all require lifelong care.

This occurs when babies are born with a hole in the wall between the heart’s two lower chambers. Often but not always, surgery is performed early in life.

When the center of the heart does not form correctly, there is at least one hole and abnormality of the valves.
