NON-NEWTONIAN BEHAVIOR SIGNIFICANTLY AFFECTS HEMODYNAMIC EFFICIENCY IN A FOUR-DIMENSIONAL FLOW MAGNETIC RESONANCE FONTAN MODEL

The non-Newtonian behavior of blood (i.e. the dependence of viscosity on shear rate and shear stress) is most apparent in low-shear regions such as veins. For simplification, computational simulations aimed at optimizing the Fontan procedure have assumed blood to be a Newtonian fluid with shear
