RESUMO
Between April 1992 and April 1994, 185 patients were waiting for a cardiac transplant at our institution. Transplantation was performed in 118 of these patients. Twenty-six patients (14%) died while awaiting a donor heart: 13 of these were in the intensive care unit on multiple inotropic medications, mechanical support, or both; another 13 were either in the hospital on a single inotropic medication or at home with or without inotropic support. The remaining 41 patients were still awaiting transplantation at the end of the study period. During the same interval, 20 comparably ill patients who were referred to our institution for transplantation were considered for high-risk conventional surgical procedures. These patients underwent clinical evaluation to determine whether they had viable muscle that was salvageable and electrophysiologic status that was alterable. On this basis, these 20 patients underwent a variety of combined high-risk procedures. Two patients died; the operative mortality was 5% and the cumulative mortality was 10%. We conclude that these initial results support our original impression that mortality rates are higher in patients waiting for cardiac donation than in patients undergoing high-risk surgical procedures. Therefore, we will continue to investigate high-risk conventional surgery as an alternative to cardiac transplantation.
