what is the mitroflow bioprosthesis made of
The Sorin Mitroflow is a bioprosthetic valve that is used to repair a damaged valve in patients with valvular heart disease. This type of heart valve is made from animal tissue and is often used in children born with congenital heart disease. It allows surgeons to repair a heart valve in children and young adults until they are old enough to receive a more durable mechanical valve. Bioprosthetic valves are expected to be replaced after 8 years, but surgeons are noticing that the Mitroflow valve is failing much earlier â sometimes in less than two to three years after placement.
