Özet
This study aimed to evaluate thrombosis and bleeding events in the children implanted with two types of ventricular assist devices (VAD). A total of 26 paediatric end-stage heart failure patients with the mean age of 11.32 ± 4.17 years, 15 were boys, implanted with a VAD, either the Berlin Heart EXCOR (BHE group; n = 9) or the HeartWare (HW group, n = 17), were included in this retrospective study. Follow up data on bleeding events, thrombosis events, bridge-to-transplantation rates and survival outcome were recorded. Overall, 16(33.3%) bleeding events and 32(66.7%) thrombosis events occurred, while 14(53.8%) patients had at least one thrombotic event and 8(30.8%) patients had at least one bleeding event. BHE and HW groups were similar in terms of number of patients with at least one thrombotic (33.3% vs. 64.7%, p = .218) or bleeding (22.2% vs.35.3%, p = .399) event. Mortality occurred in 9(34.6%) patients and 13(50.0%) patients achieved bridge-to-transplantation, similarly in BHE and HW groups (mortality: 44.4% vs. 29.4%, p = .667 and transplantation: 77.8% vs. 35.3%, p = .097). In conclusion, our findings revealed that VAD application in children with heart failure enables successful heart transplantation achievement with an acceptable risk of bleeding/thromboembolic events in most of cases. More advanced VAD technologies and more successful management for haematologic complications are necessary to improve the transplantation rates in children.
