In this condition, the valve does not close properly and blood flows back into the right atrium. It is often associated with or due to an enlarged right ventricle. The most common reason for leakage of this valve is high pulmonary pressures caused by a damaged mitral valve. This enlargement may also be related to a severe, long-standing lung disorder, such as emphysema or pulmonary hypertension, or by a narrowing of the pulmonary valve (pulmonary stenosis). When the right ventricle enlarges and thickens so that it can pump harder, the valve opening stretches.

The tricuspid valve is not keeping all of the blood in the chambers of the heart seperate as the heart is beating the blood through - ie - some of the blood is leaking back.
