Severe mitral annular calcifi cation in rheumatic heart disease:A rare presentation

摘要

Severe mitral annular calcification(MAC)is frequently seen in patients with advanced age and chronic kidney disease,but it is rare in rheumatic heart disease(RHD).We hereby report a case of 45-year-old female with chronic RHD,who had severe MAC and mitral regurgitation.Fluoroscopy revealed a "crown"-like severe calcification of the mitral annulus.Autopsy of the heart revealed a calcified posterior mitral annulus,fused commissures,and calcified nodules at the atrial aspect of the mitral valve.
