A calcified left ventricular mass.

Mitral annular calcification is a degenerative process. It is mostly asymptomatic. As the calcification becomes more extensive it might be mistaken for an intracardiac tumour. Mitral annular calcification predicts cardiovascular events, cardiovascular death and overall death. It is predictive of a doubling of the stroke risk. Extensive mitral annular calcification may undergo liquefaction. Surgery is seldom needed.
