(rollover to compare with normal) What Is It?

Atrioventricular Septal Defect, also known as Atrioventricular Canal Defect, is actually a combination of defects, involving malformations of the tricuspid and mitral valves. In some cases, the mitral and tricuspid valves are connected, forming a single opening. In addition to valvular defects, defects (in the form of holes) often occur in both the ventricular septum (VSD) and the atrial septum (ASD).
