Mitral regurgitation due to caseous calcification of the mitral annulus: Two case reports

Abstract

Caseous calcification is a rare variant of mitral annular calcification, occurring in about 0.06% of echocardiographic studies performed. It is usually a benign lesion, but it should be differentiated by abscess and tumors. Echocardiography is the most sensitive method to identify caseous calcification which appears typically as a round, calcified mass with an echo-lucent, liquid-like inner part. © 2009 Marcì and Lo Jacono; licensee BioMed Central Ltd.
