A case of mobile mitral annular mass

Mitral annular calcification is a chronic, degenerative process of the mitral valve fibrous ring, primarily involving the posterior annulus. This report presented a case of mitral annular calcification with mobile components which was found incidentally during TTE. The echocardiographic differential diagnosis of a mass includes thrombus, vegetation, primary or secondary cardiac tumor and extensive mitral annular calcification with mobile components. A calcified, mobile mass attached to the posterior mitral annulus should raise the suspicion of extensive mitral annular calcification. Serial echocardiograms in our patient documented that these mobile elements can resolve rapidly. The optimal treatment or clinical approach to this clinical condition remains to be established.
