An interrupted aortic arch (IAA) is a rare heart defect. The aortic arch is part of the major blood vessel that helps move blood from the heart to the rest of the body. With IAA, the aortic arch is interrupted or incomplete. Blood cannot flow the way it should. Children with IAA may also have a hole in the wall between the right and left chambers in the heart.
