Fig. 13A,B: Mitral annular/valve calcification. (A) Calcification in the region of the Mitral valve (arrow). This is not surrounded by pericardial fat like the LCX. (B) Calcification in the region of the mitral annulus (arrow). This can be very close to the GCV and the LCX (circle). This is surrounded by cardiac muscle and is very angular in appearance, helping to distinguish this from the true LCX calcification.
