1 Sometimes, a patient's own tissue can be used for valve replacement (called an autograft). 2  Patients with biological valves usually do not need to take blood-thinning medicines. 3  These valves are not as strong as mechanical valves, though, and they may need to be replaced every 10 years or so.
The mitral valve regulates the flow of oxygen rich blood from the lungs to pass from the left atrium to the left ventricle.There are two main diseases or malfunctions of heart valves: regurgitation (valve does not close tightly) and stenosis (valve does not open fully).he mitral valve is also prone to a disease referred to as mitral valve prolapse. With mitral valve prolapse, the mitral valve bulges slightly back into the left atrium when it closes, allowing a small amount of blood to leak backward. Mitral Valve Insufficiency/Regurgitation.
