Coding Notes

The intravalvar variant is distinguished from the supravalvar variant because the intravalvar ring is within the funnel of the mitral valvar leaflets. Both the intravalvar variant and the supravalvar variant are differentiated from divided left atrium because in the latter the posterosuperior compartment contains the pulmonary veins while the antero-inferior contains the left atrial appendage (and the atrioventricular valve [usually mitral valve] in the absence of left atrioventricular valvar atresia); in supravalvar or intravalvar mitral ring, the antero-inferior compartment contains only the mitral valve orifice and not the left atrial appendage.
