Overview
Endocardial cushion defects are often called atrioventricular canal or septal defects. This is not a single defect but a variety of defects that involve the atrial septum, one or both of the atrioventricular valves, or the ventricular septum.
Classification
There are two broad classes of defect:
- Partial defects: There is atrial septal involvement, but there are separate mitral and tricuspid valve orifices.
- Complete defects: There is the presence of both atrial and ventricular septal defects and there is a common AV valve.
