Simulation of 75% arterial stenosis reveals a distal wall vortex creating a local pressure minimum.
Mathematical simulation of a 75% arterial stenosis demonstrates the development of distal and proximal vortices during the cardiac cycle due to flow reversal and pressure-kinetic energy conversion.

Does not alter stenosis management; leaves open whether post-stenotic vortices influence plaque progression in vivo.
Wille et al. (1981) studied Arterial stenoses. Mathematical simulation of 75% constriction stenosis model was evaluated on Pulsatile pressure and flow velocity patterns. Mathematical simulation of a 75% arterial stenosis model showed that a vortex develops at the wall distal to the stenosis as velocity decreases from peak systole, creating a local pressure minimum.
