MAC is usually seen with which cardiac condition?

• A. HOCM
• B. Renal failure
• C. AS
• D. Severe chronic hyperparathyroidism

Answer: (C)

Mitral annular calcification is a degenerative process of the fibrous ring around the mitral valve. It tends to be seen most commonly in the setting of calcific valvular disease of the aortic valve, especially calcific aortic stenosis. Both conditions share risk factors such as aging, hypertension, atherosclerotic changes, and chronic kidney disease, so the presence of MAC often accompanies calcific aortic valve disease. On imaging, MAC appears as bright calcific densities along the mitral annulus and can be associated with mitral valve dysfunction, but its strongest, most classic association in practice is with aortic stenosis. While metabolic conditions like renal failure or severe hyperparathyroidism can contribute to calcification, they are not as consistently linked to MAC as calcific aortic stenosis.
