Quizplus · Accepted Answer

The average lifespan of biologic and mechanical heart valve replacements ranges from 10 to 15 years. While mechanical valves have the potential to last indefinitely, they require lifelong anticoagulation therapy and may have a higher risk of thrombosis and bleeding complications. Biologic valves, which are made from animal tissue, may not require anticoagulants but have a shorter lifespan. The choice of valve replacement depends on the patient's age, health status, and individual preferences.
