... The tricuspid valve is between the right atrium and right ventricle. It has three triangular cusps (leaflets). It opens as the right atrium contracts to allow blood to flow from the right atrium into the right ventricle. Then it closes to prevent blood from flowing back into the right atrium. The pu ...

Mitral insufficiency



Mitral insufficiency (MI), mitral regurgitation or mitral incompetence is a disorder of the heart in which the mitral valve does not close properly when the heart pumps out blood. It is the abnormal leaking of blood backwards from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts, i.e. there is regurgitation of blood back into the left atrium. MI is the most common form of valvular heart disease.
