In clinic in the period from 2012 to 2014 in 142 patients were performed interventions on the mitral valve for coronary heart disease and ischemic mitral valve insufficiency (MVI). The majority of patients were able to work, its witness for social-economic significance of problem. The main reason of the ischemic MVI arised were the dilatation of mitral valve fibrousing and substitution of papillar muscles for left ventricle remodelling. Symmetrical deformation of mitral valve arised in most cases after anterior-septal myocardium infarction, left ventricle global remodelling and apical substitution of papillar muscles; asymmetrical ones--after posterior myocardial infarction for local left ventricle papillar muscles.
