Abstract
Mitral ring calcification is the commonest abnormality found in elderly patients with systolic murmurs (1, 2). Extensive calcification of the mitral valve annulus which may produce variable degrees of mitral regurgitation can be strongly suspected in individuals over 50 years of age with systolic apical murmurs and no history of previous rheumatic heart disease. Calcified mitral annulus (CMA) is found in about 10% of autopsies in patients over age 50.
