Prosthetic heart valves

Abstract

Biological and mechanical heart valves have their own advantages and disadvantages. Mechanical valves have good durability but also have risk of causing anticoagulant related complications. Biological valves have less durability compared to mechanical valves. Biological valve is an ideal option for geriatric patients who have multiple co-morbidities and low (<15 years) life expectancy 13. It is also good option for adult patients who are reluctant to take anticoagulant therapy. The mechanical valve is preferred for adult patients who have life expectancy of more than 30 years and are willing to take anticoagulant therapy 13. It is also a good option for geriatric patients who have no co-morbidity and are willing to take anticoagulant therapy. The choice between mechanical and biological heart valves depend upon patient's age, associated co-morbidity, life expectancy and patient's preferences, such as, willingness to take anticoagulation therapy, reoperation and lifestyle changes after surgery.
