European homograft bank: twenty years of cardiovascular tissue banking and collaboration with transplant coordination in Europe.

Abstract：

:Established in 1989 in Brussels as an international nonprofit association, the European Homograft Bank (EHB) has been collaborating closely with the transplant coordination of the different centers in Belgium and other European countries. Donor selection is made after discussion of exclusion criteria with the transplant coordinator of the procurement center. EHB collaborates with 15 Belgian, 11 German, 10 French, 10 Swiss, 3 Italian, 3 Dutch, and some other procurement and/or implantation centers. Donor ages range from newborn to 65 years. Tissue preparation, morphologic evaluation, and functional testing are performed under Class A laminar flow. After decontamination in a cocktail of 3 antibiotics (lincomycin, vancomycin, and polymixin B) during 20-48 hours, the tissues cryopreserved with liquid nitrogen to -100 degrees C are stored in vapors of liquid nitrogen below -150 degrees C for a maximum of 5 years. Systematic virologic examination of donor blood is performed for HIV, HTLV, hepatitis B/C, and syphilis, as well as for enteroviruses, Q fever, malaria, and West Nile virus by indication. Bacteriologic examination for anaerobic and aerobic contamination is performed at the different steps of processing. Histologic examination for malignant disease and infection is performed systematically. Indications for implantation are discussed with the requesting surgeon. Transport to the implantation center is carried out safely in a dry shipper at -150 degrees C or in dry ice at -76 degrees C. The EHB received 4,511 hearts and 1,169 batches of arteries from January 1989 to December 2008. The 5,133 heart valves (1,974 aortic, 3,106 pulmonary, and 53 mitral) and 2,066 arterial segments have been prepared and stored; 4,600 cryopreserved valvular (2,717 pulmonary, 1,835 aortic, and 48 mitral) and 1,937 arterial allografts have been distributed for implantation in various European Cardiovascular Centers. EHB is not always able to meet the increased demand for heart valves and arterial allografts. Collaboration between the EHB and the Transplant Coordination is satisfactory. Donor selection criteria are discussed with the transplant coordinator; whereas, implantation indication, with the implanting surgeon. Because the EHB is not always able to meet demands for the cryopreserved valves and arterial segments, there is a need to increase number of procurements. Cardiovascular surgeons need to play more active roles in the resolution of this problem.
