COSTA, Marise Teresinha Brenner Affonso da et al. Analysis of the inicial eight years of activities of the Human Heart Valve Bank of the Hospital de Caridade da Irmandade da Santa Casa de Misericórdia de Curitiba. Rev Bras Cir Cardiovasc [online]. 2005, vol.20, n.4, pp.398-407. ISSN 0102-7638.

OBJECTIVE: The aim of this study was to retrospectively evaluate the first eight years of activities of the Human Heart Valve Bank of Hospital de Caridade da Irmandade da Santa Casa de Curitiba (BVCHSC), analysing aspects related to procurement, processing, storage and distribution of homologous cardiovascular grafts. METHOD: Initial donor screening was achieved according the national guidelines for human organ procurement, besides specific BVCHSC criteria. Hearts were obtained from multiple organ donors, non-beating heart donors and heart transplant recipients, with total ischemic times under 48 hours. Donor ages varied from neonates up to 60 years for aortic valves and 65 years for pulmonary valves. The dissected grafts had their dimensions measured and their morphology evaluated, using a classification system with category 0 (discarded), 1 (minimal morphological alterations) and 2 (perfect). The incidence and microorganisms responsible for organ contamination were determined, as was the efficiency of the decontamination solution. Aspects related to graft distribution were also analysed. RESULTS: From September 1996 to February 2005, 1059 hearts from 19 Brazilian states were recevied at BVCHSC. From these, 977 (92.3%) were from brain-death donors. A total of 2105 grafts were processed and of the aortic and pulmonary grafts that were analysed, 783 were in category 2, 697 in category 1 and 186 were discarded due to morphological abnormalities. In total, 433 received grafts were contamined and the sterilization solution was efficient in 330 cases. 571 (27.1%) grafts were rejected during some phase of the processing, mainly due to contamination and morphological abnormalities. A total of 1338 grafts were distributed to 74 health institutions and were more commonly used for aortic valve replament (529), correction of congenital heart diseases (478) and during the Ross procedure (272). CONCLUSIONS: The activities of the BVCHSC during the initial eight years were satisfactory, fulfilling the proposed goals.
