Popis: Objectives: In patients with thalassemia major (TM) who are non-compliant with long-term deferoxamine (DFO) chelation, survival is limited mainly because of cardiac complications of transfusional siderosis. It was recently shown in a small group of TM patients with established cardiac damage that continuous 24-h DFO infusion via an indwelling intravenous (i.v.) catheter is effective in reversing cardiac toxicity. The aim of the present study was to evaluate the results with intermittent daily (8–10 h) i.v. DFO. Patients: Eight TM patients with cardiac complications treated with intensive intermittent DFO were retrospectively evaluated by the mean annual serum ferritin, radionucleated ventriculography and 24-h electrocardiography recordings. Results: The median age at diagnosis of cardiac disease was 17.5 yr (range 14–21), and the median follow-up time was 84 months (range, 36–120). In the majority of patients (seven of eight) high-dose DFO (mean 95 ± 18.3 mg/kg/d) was administered via a central venous line. During follow-up, there was a significant decrease in the mean ferritin levels (5828 ± 2016 ng/mL to 1585 ± 1849 ng/mL, P
