Severe tricuspid valve insufficiency is caused by right ventricular and pulmonary artery disease, the main risk factor is right heart failure, and the common symptom is lower extremity edema. Severe tricuspid valve insufficiency without treatment has a survival time of less than 5 years, and the main cause of death is heart failure complicated by atrial fibrillation or thrombus dislodgement leading to pulmonary embolism. Mild tricuspid valve insufficiency is not clinically specific and does not produce significant discomfort, but in more severe cases symptoms of fatigue, loss of appetite, abdominal distention, or lower extremity edema may occur. After active treatment to develop symptoms of heart failure, at least 20 years, life expectancy is basically comparable to normal people. Early symptoms of weakness can be seen more rest and less strenuous exercise, which will not exacerbate the development of the disease, with timely control of pulmonary infections, and if lower limb edema occurs, hydrochlorothiazide or tachyphylaxis with metoprolol can be used.
