Top: Pressure waveform results from simulations using 3-element and 5-element LPN outlet boundary conditions (blue and orange solid lines, respectively) with Womersley inlet flow profile, pressure gradient of the 3-element and 5-element pressure waveforms (blue and orange dashed lines, respectively), and intramyocardial pressure from the 5-element LPN (yellow line). The location shown corresponds to the region of elevated OSI in Fig. 5, which is two diameter distances from the inlet. Bottom: Enhanced cross-sectional view showing velocity magnitude percent difference at timepoints A and B (left). Differences in velocity magnitude were calculated by subtracting velocities of the 3-element LPN outlet boundary condition simulation from those of the 5-element LPN outlet boundary condition generally within the red ellipse. Velocity differences between the 5-element and 3-element LPN outlet boundary condition simulations are shown for vectors and contours located at a depth of approximately half the strut thickness below the lumen surface (middle) and in cross-section (right).
