a Shear stress histograms for the three pump systems for 0.5 L/min, low- and high-pressure head (150 and 250 mmHg). The blood volume of impeller and secondary gaps associated with a certain shear stress interval (x-axis) is plotted (DP3, 9.5 mL; Rotaflow, 18.2 mL; Revolution, 48 mL). The shear stress interval between 0 and 5 Pa contains most of the associated volume and was not shown for an improved view. Figure 4b details the associated volume above 100 Pa. c Volume rendering of shear stresses above 50 Pa illustrating potential hotspots within the pumps
