Surgical Outcome
Mechanical Versus Biological Valves
Mechanical heart valves do not fail often. They last from 12 to 20 years. However, blood clots develop on them. If a blood clot forms, the patient may have a stroke. Bleeding can occur, but this is rare. Biological valves tend to fail over time [1][2], but they have a lower risk of blood clots.
