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.
Along with scarring of the veins, a blood clot may injure the valves (two leaflets lying in the vein which shut to stop the backward flow of blood) causing incompetence and deep venous reflux or back flow (Figure 1) . This will allow the blood togo backward in the vein and down the leg rather than up to the heart.
