[Mitral valve fibrous ring calcinosis in ischemic heart disease].

Calcinosis of the mitral fibrous ring (CMFR) was detected echocardiographically in 11.7% of the examinees with ischemic heart disease (IHD) at the age over 60 years. In CMFR the mitral opening significantly narrows, maximal transmitral diastolic gradient rises, mitral regurgitation becomes more pronounced. In one-third of the patients calcinosis involves the posterior wall disturbing its kinematics. Narrowing of the mitral opening in IHD patients accompanying CMFR is considered to be moderate nonvalvular mitral stenosis.
