Tricuspid Regurgitation

Tricuspid regurgitation is a disorder involving backflow of blood from the right ventricle to the right atrium during contraction of the right ventricle. The most common cause of tricuspid regurgitation is not damage to the valve itself but enlargement of the right ventricle, which may be a complication of any disorder that causes right ventricular failure.
