Why the study?
Caseous calcification of the mitral annulus is rare, often misdiagnosed, and in association with comorbidities can potentially increase the risk of cerebrovascular accidents.
This case highlights the rare association of caseous calcification of the mitral annulus and hypertrophic obstructive cardiomyopathy as a potential cause of cardioembolic stroke.

May prompt stroke etiology evaluation in MAC with HOCM; leaves open prevalence and causality of this association.
Caseous mitral valve calcification and concurrent hypertrophic obstructive cardiomyopathy: A rare cause of stroke Mitral annulus calcification (MAC) is a relatively common condition with a prevalence of about 14%, often seen at old age and results from degenerative changes in the mitral valve fibrous skeleton [1].An exceedingly rare and adverse variant of MAC is the caseous calcification of the mitral annulus (CCMA), which accounts for only 0.6% of all MAC cases [2].It can be easily confused with tumors, vegetations, or cysts; thus, often underdiagnosed and mistreated.CCMA in association with other comorbidities can potentially increase the risk of cerebrovascular accidents (CVA).Here, we present the first case of CCMA with concomitant hypertrophic obstructive cardiomyopathy (HOCM) presenting with cardioembolic stroke complicated by hemorrhagic conversion.
