Calcified disease of the mitral annulus: a spectrum of an evolving disease.

Mitral annulus calcification may appear under different forms depending from its evolution stage: mitral annulus calcification; homogeneous calcified mass of the mitral valve; liquefaction necrosis of the mass; reduction or stability of the mass dimension. We report a large calcified mass located in between the posterior mitral valve leaflet and adjacent left ventricular myocardium suggesting the homogeneous calcified phase of the disease.
