What is an Atrial Septal Defect?

An atrial septal defect (ASD) is a congenital heart defect that allows blood to pass between the left and right atria via the interatrial septum. When this septum is missing or defective, venous blood and arterial oxygen-rich blood can mix and be pushed throughout the body with less oxygen than is needed. One specific type of ASD is patent foramen ovale (PFO).
