The objective of this paper is to study the effects of compliance mismatch in a stented artery. COMSOL Multiphysics is used to tackle this challenging problem involving fluid-structure interaction.

The particular effects studied in this paper are the radial displacement of the artery wall, pressure distribution along the studied segment, the factors affecting stress in the fluid and artery wall, vorticity, etc. The attention is focused on abnormal behaviors near the proximity of the stented portion. It is found that a greater compliance mismatch increases the perturbation of the hemodynamics and structural mechanics of the wall.
