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.
Most valve repair and replacement operations are successful. In some rare cases, a valve repair may fail and another operation may be needed. Patients with a biological valve may need to have the valve replaced in 10 to 15 years. Mechanical valves may also fail, so patients should alert their doctor if they are having any symptoms of valve failure. Patients with a mechanical valve will need to take a blood-thinning medicine for the rest of their lives.
