Regurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart. The valves in your heart may be damaged due to infection, rheumatic heart disease, wear and tear, tissue weakening or deterioration, or birth (congenital) defects.egurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart.

See a picture of blood flow through a normal heart. When disease or an infection damages a heart valve, it can cause scarring and can affect how well the valve works. The valve may not be able to close properly, so blood can leak through. Or the valve may become too narrow or stiff to let enough blood through.
