A numerical analysis is performed in order to study coronary artery wall shear stress (WSS) and its dependence on (i) unsteadiness of the flow, (ii) motion and deformation of the blood vessel geometry and (iii) the shear thinning properties of blood. A non-stationary geometric model of the right coronary artery is developed from intravascular ultrasound measurements complemented with the 3D reconstructed measurement location and orientation. The velocity distribution in the model is computed by solving the arbitrary Lagrangian-Eulerian (ALE) formulation of the Navier-Stokes equations using a finite-element method. The averaged WSS pattern corresponding to time-dependent shear thinning flow in the non-stationary model is compared to the pattern corresponding to steady mean Newtonian flow in the rigid end-diastolic model
