Each heart valve has two important functions: To open correctly so that blood can empty from the chamber. To close properly so that blood cannot flow the wrong way. When the valves and chambers fail to move blood properly, symptoms may eventually develop and may require critically important treatment. Learn more about the roles of your heart valves.
This means the valve doesn't close completely, causing the blood to flow backward through the valve. This results in leakage of blood back into the atria from the ventricles (in the case of the mitral and tricuspid valves) or leakage of blood back into the ventricles (in the case of the aortic and pulmonary valves).
