VALVULAR INSUFFICIENCY is a condition in which incomplete valve closure results in backflow of blood.

Explanation:

Valvular insufficiency which is also known as incompetence, or leaky valve occurs when a valve does not close tightly. Valves that do not seal will lead to some blood leaking backwards across the valve. The heart has to work harder to make up for the leaky valve as the leak worsens, and less blood may flow to the rest of the body. The condition is called tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, or aortic regurgitation depending on which valve is affected
