Caseous calcification of the mitral annulus: case report and brief review.

ABSTRACT:

Background

Caseous calcification of the mitral annulus (CCMA) is a very rare variant of mitral annular calcification, which is typically asymptomatic but can manifest as a cardiac tumour, abscess, or in the form of mitral valve dysfunction.

Case summary

We present a patient who developed shortness of breath and was initially thought to have an intracardiac tumour, but ultimately was recognized as massive calcification of the mitral valve by computed tomography angiogram. This finding was unfortunately made only shortly before the patient's clinical deterioration, and the specific diagnosis of CCMA was made on post-mortem findings, precluding any directed treatment for this entity.

Discussion

Caseous calcification of the mitral annulus can lead to significant pathology, including mitral regurgitation, stenosis, or systemic embolization of caseous material. Due to its relative scarcity and tendency to be asymptomatic, a diagnosis of CCMA is often difficult to make or easily overlooked. Early recognition and appropriate treatment is crucial for avoiding these potential complications.
