Caseous Calcification of the Interventricular Septum Leading to Left Ventricular Outflow Tract Obstruction in the Setting of a Normal Mitral Valve Annulus

Caseous calcification of the mitral annulus (CCMA) is a rare pathology and considered a unique variant of mitral annular calcification (MAC). It is often diagnosed with the use of echocardiography where it is described as a large, heterogenous, echodense mass near the mitral annular region.1 It is a unique form of intramyocardial calcification and its central areas of echolucency, resembling liquefaction, distinguish it from the more commonly known dystrophic calcification.1,2 While its exact prevalence is unclear, some studies have mentioned it to be as rare as occurring in only 0.06% of the population.
