Coding Notes

In differentiating cor triatriatum from supravalvar mitral ring, in cor triatriatum the posterior compartment contains the pulmonary veins while the anterior contains the left atrial appendage and atrioventricular junction (usually the mitral valve); in supravalvar mitral ring, the anterior compartment contains only the mitral valve orifice.
