Background. Calcification of various cardiovascular structures is associated with aging. Mitral annular calcification (MAC) is a chronic degenerative process of the mitral valve ring; it was first described in 1908 by Bonninger as associated with complete heart block.aseous calcification of the mitral valve is a rare form of MAC that typically affects the posterior annulus. The contents of the cavity are composed of a mixture of calcium, fatty acid, and cholesterol, with a ââtoothpaste-likeââ texture, and may present as an intracardiac mass or cavity.
