What is the movement of mitral valve calcification?

Mitral calcification: Under certain circumstances and with advanced age, the leaflets of the mitral valve can become loaded with calcium. This makes the leaflets stiffer and can limit the opening of the valve (mitral stenosis), causing a restriction of blood flow through the heart. There is another form of calcification in the mitral ring which usually does not cause any symptoms.

Stiffness: Valvular calcification causes stiffness of the leaflets structure -- it could cause restriction or regurgitation of the valve.

Back & forth: During the cardiac cycle, mitral annular calcification can be observed to move to & fro on real time echocardiography.
