Chunky Mitral Annular Calcification: Caseoma or a Tumor?

TL;DR

This paper discusses a rare heart condition called caseous mitral annular calcification that can resemble a tumor on imaging and needs proper diagnosis.

Contribution

The paper highlights the diagnostic challenges of caseous mitral annular calcification, emphasizing its similarity to cardiac tumors.

Findings

Caseous mitral annular calcification is a variant of MAC that can mimic a cardiac tumor on echocardiography.

Differentiating caseous MAC from tumors is clinically important to avoid unnecessary interventions.

MAC is more common in females and in patients with end-stage renal disease.

Abstract

Mitral annular calcification (MAC) is relatively common in clinical practice. Females are more often affected than males. Patients with end-stage renal disease have MAC relatively more commonly than the general population. Patients with MAC often develop conduction system disturbances, including advanced atrioventricular blocks. They are also more likely to develop various arrhythmias, including atrial fibrillation. Caseous mitral annulus calcification is a variant of MAC that often looks like a cardiac tumor on an echocardiogram and needs to be differentiated.
