Abstract
Mitral annular calcifications (MACs), calcifications of the mitral annulus, are chronic degenerative changes that occur mostly along the posterior mitral leaflet. The incidence of MACs increases in the presence of end-stage renal disease (ESRD) and atherosclerosis risk factors such as hypertension, diabetes, and dyslipidemia. MACs can also be associated with liquefied necrosis or caseous calcification.1, 2 Calcified amorphous tumors (CATs) constitute rare non-neoplastic masses of the heart that are histologically composed of calcium deposits, inflammatory cells, and fibrin elements. The etiology of CATs is still unclear.3, 4, 5 Subgroups of cardiac CATs are echogenic spindle-shaped masses that arise from the mitral valve and are frequently related to bulky MACs in patients with ESRD; they are termed “MAC-related CATs.”5 Herein, we present a case of a CAT that arose from a MAC in a patient with ESRD and discuss the diagnostic features and management of this patient.
