1. Today, cryopreservation is the method of choice for homograft preservation. 2. Homograft valves are donated by patients and recovered after the patient expires.3. Homograft valves are donated by patients and recovered after the patient dies.4. In some cases a homograft -a human aortic valve can be implanted. 5. The durability of homograft valves is comparable to porcine and bovine tissue valves. 6. In 1962 Ross introduced the use of homografts to replace diseased aortic valves. 7. The durability of homograft valves is probably the same as for porcine tissue valves. 8. Despite early promise, homografts had a limited life span of around 8 years. 9. The pulmonary valve is then replaced with a donor graft from a diseased person ( a homograft ). 10. The institute will recommend the potential homograft patients to the Have-a-Heart Fund committee for sponsorship.
