mitral annular calcification
Mitral annular calcification is a chronic process in which there is deposition of calcium in the mitral valve annulus. The mitral annulus is typically flexible. In mitral annular calcification it becomes less flexible and thicker.everal studies have looked at the association of mitral annular calcification and the development of cardiac and other events. There is increased risk of heart attacks, stroke and death from cardiovascular causes. There is also an increased risk of development of atrial fibrillation with RVR, an irregular heart rhythm.
