Question 54
F

A 25 year old patient needs a faulty heart valve replaced. The patient can be given a biological valve or a mechanical valve.

A biological valve is taken from a cow, a pig or a human donor. A mechanical valve is made from metal and plastic.

Evaluate the use of a mechanical valve rather than a biological valve for this patient.
