Tricuspid insufficiency (TI) a valvular heart disease also called tricuspid regurgitation (TR) refers to the failure of the heart’s tricuspid valve to close properly during systole. As a result with each heart beat some blood passes from the right ventricle to the right atrium the opposite of the normal direction. Tricuspid regurgitation occurs in roughly less than 1% of people and is usually asymptomatic.
