Mild tricuspid regurgitation can live a normal life expectancy, while severe regurgitation can lead to complications that can affect life expectancy. The tricuspid valve is a one-way valve between the left and right ventricles and the right atrium to ensure that when the heart ejects blood, the blood cannot flow backwards from the right ventricle into the right atrium. Mild and asymptomatic tricuspid regurgitation does not affect the heart’s function so it does not need to be treated and only requires regular checkups. However, severe tricuspid regurgitation may lead to decreased heart function after a long period of time, and in severe cases, complications such as edema, dyspnea, and liver failure may occur. These complications may shorten the patient’s life span depending on the severity, and in severe cases, may be life-threatening, so they need to be treated carefully. In more serious cases, diuretics such as furosemide, vasodilators such as enalapril, cardiotonic drugs such as digoxin, or surgical treatments such as tricuspid valve repair or tricuspid valve replacement can be used according to the doctor’s analysis of the regurgitation situation. With timely and proper treatment, life expectancy can be greatly extended, but it may be shortened in people with serious complications. Patients with tricuspid regurgitation should go to the hospital in time and be treated according to the doctor’s instructions to avoid delays.
