Overview
Prior to surgery, the surgeon and patient must make a choice as to whether a mechanical or bioprosthetic valve should be inserted.
Advanatges of A Mechanical Valve
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. Anticoagulation with warfarin will be required which can be associated with bleeding.
Advantages of A Bioprosthetic Valve
Biological valves do not require anticoagulation, but they tend to fail over time [1][2]. Patients with a biological valve may need to have the valve replaced in 10 to 15 years.
