Abstract: The performance of an axial flow blood pump in an idealized total cavopulmonary connection (TCPC) model was intravascularly evaluated. This blood pump was inserted within a modified Fontan surgery using a reinforced Gore-Tex conduit, to be connected to the caval veins with the pulmonary arteries. Two different computational models were examined (i) the new geometric model without a pump and (ii) with the pump. Computational fluid dynamics analyses of these models were performed to assess the hydraulic performance under varying pump’s operating conditions. Numerical simulations indicate that the pump generates a pressure distribution which could prove to be beneficial for the univentricular patient with failing Fontan circulation, allowing to provide a possible intervention, at least as bridge to heart transplantation or as end-stage pump implant.
