The tricuspid valve separates the right lower heart chamber (the right ventricle) from the right upper heart chamber (right atrium). The most common cause of tricuspid regurgitation is swelling of the right ventricle. Such swelling may be a complication of any disorder that causes failure of the right ventricle. Tricuspid regurgitation may also be caused by or made worse by valve disease on the left side of the heart such as mitral regugitation and mitral stenosis. Other diseases can directly affect the tricuspid valve. The most common of these is rheumatic fever, which is a complication of untreated strep throat infections. Tricuspid regurgitation may be found in those with a type of congenital heart disease called Ebstein's anomaly.
Other infrequent causes of tricuspid regurgitation include:
Carcinoid tumors, which release a hormone that damages the valve Marfan syndrome Injury Rheumatoid arthritis Radiation therapy
Another important risk factor for tricuspid regurgitation is use of the diet medications called "Fen-Phen" (phentermine and fenfluramine) or dexfenfluramine.
