An AV Canal diagnosis typically consists of two different abnormalities occurring at the same time. The first is called an Atrioventricular Septal Defect (ASD) – a relatively common congenital heart defect. ASD is an open hole between the top chambers. The second condition, Ventricular Septal Defect (VSD), means that the mitral and tricuspid valves are combined into a single common AV valve. The lungs receive more blood flow than normal because of the ASD and VSD. Since more blood flow is pumped into the lungs, the heart has to work harder to pump blood to the body.
