Mitral valve calcification refers to calcification of the mitral valve membrane, mostly on cardiac ultrasound and chest imaging suggesting calcium salt deposits. Mitral valve calcification can be seen in valvular disease, such as mitral stenosis and mitral valve closure insufficiency. In addition, it can be seen in infectious myocarditis or endocardial lesions that result in calcium salt deposits. Mitral valve calcification can affect the function of the mitral valve, thus affecting the diastolic and systolic functions of the heart. Treatment of mitral valve calcification is primarily directed at the primary disease. If mitral valve calcification causes moderate to severe mitral stenosis or incomplete closure, surgical treatment is often required. Drug therapy can only relieve symptoms, and commonly used drug treatments include anti-cardiac failure therapy in the case of heart failure, and anticoagulation and anti-arrhythmia-related therapy in the case of arrhythmias.
