Mild tricuspid valve insufficiency often occurs secondary to right ventricular enlargement and when the resistance of the right ventricular outflow tract increases, which leads to tricuspid valve insufficiency. Because the right ventricle is enlarged, the tricuspid valve of the heart cannot grow with the enlargement of the right ventricle, so the phenomenon of incomplete closure can occur. The causes of right ventricular enlargement are, in most cases, caused by pulmonary hypertension and pulmonary edema, and the causes of pulmonary hypertension should be considered pulmonary heart disease, congenital heart disease, and infectious factors, all of which may lead to the phenomenon of mild tricuspid valve insufficiency, and The regurgitation phenomenon occurs. Some patients may experience weakness and fatigue, as well as jugular venous pulsation, right upper abdominal discomfort, and in severe cases, heart failure such as lower limb edema. If the patient has weakness and ascites, pay high attention to whether it is caused by heart failure, and determine whether the patient has mild tricuspid regurgitation, if there is tricuspid regurgitation, it should be caused by incomplete closure of the tricuspid valve, so timely examination and targeted treatment are required. Mild tricuspid regurgitation usually does not require treatment, but treatment of the underlying lesion is needed. Tricuspid regurgitation is rarely treated surgically unless there are other valves that require surgery at the same time. Don’t drink alcohol, don’t smoke, avoid passive smoking, etc.
