Author(s) : ADAM M.
Type of article: Article
Summary
CRYOPRESERVED HUMAN HEART VALVES WERE PLUNGED INTO LIQUID NITROGEN, HELD FOR 5 MIN, AND THEN PROCESSED (THAWED) BY STANDARDIZED PROTOCOLS. CUSPAL TISSUES APPEARED TO HAVE NUMEROUS MICROFRACTURES OVER BOTH SURFACES OF THE TISSUE, PENETRATING INTO THE COLLAGEN/PROTEOGLYCAN MATRIX. CONTROL CRYOPRESERVED VALVES DID NOT EXHIBIT THESE MICROFRACTURES. THE CLINICAL USE OF VALVES WHICH HAVE BEEN SUBMERGED IN LIQUID NITROGEN IS DISCUSSED.
