Mild tricuspid regurgitation generally does not cause significant symptoms in patients and does not have an excessive effect on blood circulation. If the patient has no pathologic cause and no symptoms exist, only periodic review is required and no special treatment is needed. Tricuspid regurgitation is a condition in which the tricuspid valve does not close completely during closure and a small amount of right ventricular blood regurgitates into the right atrium during myocardial contraction, which increases the pressure in the right atrium and, in turn, the pressure in the body circulation. Mild tricuspid regurgitation means that the degree of tricuspid regurgitation is very mild and only a small amount of blood will regurgitate into the right atrium. It is commonly seen in degenerative heart disease, such as hypertension and pulmonary heart disease, etc. With good control of the primary disease, mild regurgitation will not progress significantly in the vast majority of cases. If the patient’s underlying heart disease is not well controlled, such as pulmonary heart disease that is not well controlled, hypertensive patients with uncontrolled blood pressure, or persistent inflammatory response to valvular heart disease, it can lead to gradual worsening of mild tricuspid regurgitation and progression to moderate or severe regurgitation. This can have an excessive impact on blood flow, leading to stasis in the body circulation and overloading of the right heart, which in turn can lead to right heart failure. Patients need to undergo regular review and follow-up observation based on cardiac ultrasound. Exercise more in life to improve body resistance and reduce the possibility of respiratory infections, and also a low sodium diet to prevent further aggravation of reflux.
