RV failure therapy-refractory right ventricular failure leading to death

Device malfunction includes technical failure of the pump itself and pump thrombosis. Neurological causes of death include haemorrhagic or ischaemic stroke. Infection comprises systemic infections, non-responsive to the applied treatment. Other causes of death include multifactorial and unknown causes of death, for example in patients in whom no autopsy was performed
