Moderate tricuspid regurgitation generally requires treatment. 1. Moderate tricuspid regurgitation usually requires active treatment, otherwise the disease will cause cardiac insufficiency and affect life expectancy. 2. Tricuspid regurgitation is caused by tricuspid valve insufficiency, in which the blood flows from the right ventricle to the right atrium during cardiac contraction, which can lead to right heart failure in the long run, and in severe cases, it can lead to total heart failure, resulting in a decrease in the quality of life, and a shorter survival period. 3. Tricuspid regurgitation can occur secondary to infective endocarditis or pulmonary hypertension. Patients may present with dyspnea, edema, weakness, arrhythmias, etc. Clinical diagnosis uses echocardiography as the gold standard. Tricuspid regurgitation should be seen as soon as it is detected, and the doctor should determine whether treatment is needed to avoid affecting survival.
