Abstract In order to improve the surgical treatment of the congenital heart
disease patient with single ventricle defect, two axial flow blood pumps, one
with diffuser and the other without diffuser, were designed and virtually
implanted into an idealized total cavopulmonary connection (TCPC) model
to form two types of Pump-TCPC physiological structure. Computational
fluid dynamics (CFD) simulations were performed to analyze the variations of
the hemodynamic characteristics, such as flow field, wall shear stress (WSS),
oscillatory shear index (OSI), relative residence time (RRT), between the two
Pump-TCPC models. Numerical results indicate that the Pump-TCPC with
diffuser More >
