Mitral regurgitation is a regurgitation of blood due to incomplete closure of the mitral valve during ventricular systole, and it cannot be self-cured. Mitral regurgitation does not require treatment if there are no clinical symptoms and regular follow-up is sufficient. If symptoms are present, angiotensinase inhibitors (captopril, perindopril) can be used to relieve symptoms. In severe cases of mitral regurgitation with cardiac insufficiency, surgical treatment should be considered. Common surgical procedures include mitral valve repair and mitral valve replacement. Mitral valve repair is suitable for those with mild valve damage, no calcification of the leaflets, and no serious thickening of the subvalvular tendon cords, and has a low operative mortality rate and a good prognosis. Mitral valve replacement is indicated for those with severe valve damage, with a higher operative mortality rate and a less favorable prognosis. Mitral regurgitation specific which option to use the treatment please hospital visit, consult the doctor.
