mitral incompetence

Failure of complete closure of the MITRAL VALVE of the heart, often as a result of damage by RHEUMATIC FEVER or coronary artery disease. The result is regurgitation of blood into the left ATRIUM when the VENTRICLE contracts so that the heart has to work harder to maintain the circulation. This leads to compensatory thickening of the muscle (heart enlargement) and sometimes HEART FAILURE. Valve replacement may be necessary.
