| Popis: | Early cardiac complications after autologous bone marrow transplantation (ABMT) were recorded for 49 children with haematological malignancies. There was no procedure-related mortality and only two cases of early post-transplant cardiac complications of clinical relevance, both of which were reversible. For 35 long-time survivors (median follow-up 7 y) serial evaluations before and after ABMT included ECG, chest radiography, echocardiography and equilibrium radionuclide ventriculography (RVG). One patient had frequent supraventricular ectopic beats after ABMT, a finding not previously noted. The mean left ventricular diastolic diameter (LVDD) was 104% of expected before ABMT (95% confidence interval 99-110). During the first year post-transplant LVDD was about 110% of expected, but thereafter normalization occurred. The mean shortening fraction before ABMT was 31% (CI 29-34), compared with the mean value of 34% for healthy children in our laboratory, and it ranged between 29% and 33% during the follow-up period. Mean left ventricular ejection fraction determined by RVG was 65% (CI 61-69) and mean right ventricular ejection fraction was 46% (CI 43-49) before ABMT, and they did not change during follow-up. It is encouraging that these heavily pre-treated children could be autografted without serious cardiac complications or deterioration in myocardial performance in a 5-10-y prospect, but longer follow-up is needed for a final evaluation. |
