Based on patient-specific pre-interventional and virtual stented geometries from CTA images, numerical simulation indicated that the wall shear stress (WSS) in stented segments, where the ISR occurred in one year, was lower than those without ISR, however.
It is worth noting that the estimation of WSS is best done with medical image-based computational fluid dynimics(CFD), rather than direct measurement of fluid velocities.
