Abstract

Computational Fluid Dynamics (CFD) models dedicated to the Ascending Thoracic Aortic Aneurysm (ATAA) hemodynamics have been improved over the years with Fluid–Structure Interaction (FSI) methods with prescribed patient-specific boundary conditions However, the utilization of FSI entails significantly higher computational costs. Moreover, these methods have poorly targeted the wall deformation caused by patient-specific heart movement during the cardiac cycle and other adjacent organs that may interfere with the deformation. In this work, the implementation of patient-specific wall displacement into CFD models is proposed to approximate ATAA hemodynamics, through a suitable level of computational effort. This paper compares two CFD numerical models that differ solely in including patient-specific wall displacement. The results obtained highlight the significance of this data in modelling ATAA.
