Mitral and tricuspid regurgitation is most common due to various diseases causing mitral valve, or tricuspid valve closure insufficiency. The treatment: 1, medical treatment, through diuretics, vasodilators, digitalis medication, thereby reducing pulmonary venous pressure, increasing cardiac output, to reduce mitral and tricuspid regurgitation, reduce atrial pressure, prevent the occurrence of respiratory disease, avoid infection, thereby reducing the occurrence of wind heart disease and infective endocarditis. 2, surgical treatment, for severe mitral and tricuspid regurgitation. The patient should be given mitral valve and tricuspid valve repair or mitral valve and tricuspid valve replacement if the patient does not improve through conservative medical treatment and if contraindications to surgery are ruled out. 3. For patients with a small amount of mild regurgitation of the mitral valve and tricuspid valve, which has a small impact on the size and function of the heart, it is recommended to review the cardiac ultrasound for six months to a year and no special treatment is needed.
