X-Message-Number: 3526 From: Stanton McCandlish <> Subject: CRYONICS: freezing of heart valves, tissues for transplants successful Date: Wed, 21 Dec 1994 11:01:50 -0500 (EST) ******* THERE'S LIFE IN THE DEEP FREEZE 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.
