The pulse wave propagating phenomenon is affected by changes in the mechanical properties and the geometry of the artery. The geometrical changes also affect the hemodynamics in the artery. In this study, to consider the hemodynamic effects on the pulse wave propagating phenomenon, we constructed computational aneurysmal models and analyzed the pulse wave propagation by a fluid-solid coupled method. The results show that vortices within the aneurysm caused vena contracta, which increased the pulse wave velocity locally, and the increased velocity was related to the maximum diameter of the aneurysm. This study shows the importance of the hemodynamic effects on the pulse wave propagation.
