Coding Notes

The common atrioventricular valve characteristically has 4 or 5 leaflets including superior and inferior bridging leaflets with a single annulus. The common valve may have one or two major orifices depending on the absence or presence of fusion of the bridging leaflets to each other or to the septal crest. The left ventricular zone of apposition between the superior and inferior bridging leaflets is commonly referred to as a "cleft".
