Subject: CRYONICS: freezing of heart valves, tissues for transplants successful
Date: Wed, 21 Dec 1994 11:01:50 -0500 (EST)


It sounds like science fiction, but CryoLife Inc. has succeeded in freezing
donated human heart valves, veins and tissues in liquid nitrogen, so that
when they're thawed and implanted in a patient, the tissues are still
living. "The thing that is spectacular is that after the transplant the
patient's heart functions absolutely normally," says the company's
president. The "cryopreserved" valves are usually implanted into children
under 15, who are at risk for complications when plastic or animal valves
are used. Human valves stretch as the child grows, and unlike plastic
valves, do not require blood thinner medication, which is risky for
children. (Investor's Business Daily 12/14/94 A4)
