Caseous Calcification of the Mitral Annulus: From Asymptomatic Lesion to Embolic Complication- Case Report

Abstract

Caseous calcification of the mitral annulus (CCMA) is a rare form of mitral annular calcification with a prevalence of 0.06% in the general population [1]. It is considered a benign condition, but in some cases it carries a risk for cardiovascular and cerebrovascular events. There is no consensus regarding treatment strategy and surgery is recommended for mitral valve dysfunction or thromboembolic events [2]. We present a case of surgical management of caseous mass of the posterior commissures of the mitral annulus with rapid dynamics from asymptomatic lesion to embolic complication.
