RESUMO

<p><b>BACKGROUND</b>Although heart transplantation has become a standard therapy for end-stage heart disease, there are few published studies regarding the use of transplant organs from marginal donors. Here we describe the clinical outcome we have obtained using marginal donor hearts.</p><p><b>METHODS</b>We analyzed 21 cases of orthotopic heart transplantation for end-stage heart disease performed in our department between September 2008 and July 2010. Of these patients, six received hearts from marginal donors and the remainder received standard-donor hearts. The two groups were compared in terms of both mortality and the incidence of perioperative complications such as infection, acute rejection, and right heart insufficiency.</p><p><b>RESULTS</b>The 1-year survival rate of both groups was 100%. Only one death was recorded in standard-donor group during follow-up. Patients who received marginal donor hearts (83%) experienced more early complications than did the standard-donor-heart group (13%), but the mortality of the two groups was the same. The duration of post-ICU stay was greater in the marginal donor group than in the standard-donor group, (35.5 ± 17.4) days and (21.7 ± 2.6) days, respectively (P < 0.05).</p><p><b>CONCLUSIONS</b>The use of marginal donor hearts increases the number of patients who can receive and benefit from transplants. However, it may introduce an increased risk of early complications, thus care should be taken both in the choice of patients who will receive marginal donor hearts and in the perioperative treatment of those for whom the procedure is performed.</p>

RESUMO

<p><b>BACKGROUND</b>Myocardial infarction results in tissue necrosis, leading to cell loss and ultimately to cardiac failure. Implantation of skeletal muscle satellite cells into the scar area may compensate for the cell loss and provides a new strategy for infarct therapy. Vascular endothelial growth factor (VEGF) is a promising reagent for inducing myocardial angiogenesis. Skeletal myoblast transplantation has been shown to improve cardiac function in chronic heart failure models by regenerating muscle. We hypothesized that VEGF expression and vascular regeneration increased in infarcted myocardium by skeletal muscle satellite cells, which can promote vascular producing and improve survival environment in infarcted myocardium.</p><p><b>METHODS</b>The skeletal muscle satellite cells were implanted into the infarcted myocardium in a model through ligated left anterior artery in Louis Inbrad Strain rat. Specimens were got for identifying the expression of VEGF and the density of vascular by immunochemical method at two weeks after implantation.</p><p><b>RESULTS</b>The proliferation and differentiation of the skeletal muscle satellite cell was very well. The expression of VEGF was higher in the implanted group (146.83 +/- 2.49) than that in the control group (134.26 +/- 6.84) (P < 0.05). The vascular density in the implanted group (13.00 +/- 1.51) was also higher than that in the control (10.68 +/- 1.79) (P < 0.05).</p><p><b>CONCLUSION</b>The implanted satellite cell could excrete growth factor that would induce angiogenesis and improve cell survival environment in infarcted myocardium.</p>
