Whether the heart mitral valve and tricuspid valve insufficiency is serious or not needs to be decided according to the degree of insufficiency, as follows: 1, not serious: mild mitral valve insufficiency, mild dyspnea after exertion, this condition is not serious and does not require special treatment. If tricuspid insufficiency is mild, there is no need to worry about it. 2. Severe: In moderate and severe mitral insufficiency, weakness and heart failure can occur, which is more serious, and valve repair or prosthetic valve replacement can be considered to achieve radical cure. In moderate and severe tricuspid valve insufficiency, right heart failure, weakness, abdominal distension, and often atrial fibrillation and pulmonary embolism may occur, and the best treatment is surgery, such as valve replacement and annuloplasty.
