The most common type of mitral regurgitation is mitral valve and tricuspid valve insufficiency caused by various diseases. The treatment of mitral regurgitation can be divided into medical treatment and surgical treatment: 1, medical treatment: the purpose of medical treatment is to reduce regurgitation, reduce pulmonary venous pressure, and increase cardiac output, and arterial dilators can be taken to reduce the resistance of the body circulation, reduce mitral regurgitation, reduce atrial pressure, and thus increase cardiac output; in addition, it is necessary to prevent infection, avoid infection, and prevent the occurrence of wind heart disease and infective endocarditis. 2, surgical treatment: mild regurgitation, but no relief after medical treatment or the effect is not good, can exclude contraindications after general anesthesia for mitral and tricuspid valve repair or mitral and tricuspid valve replacement.
