Why the study?
Does a proposed computational geometric model accurately reproduce the hemodynamic parameters of real aortic coarctation obtained from MRI data?
Does a proposed computational geometric model accurately reproduce the hemodynamic parameters of real aortic coarctation obtained from MRI data?
A proposed computational fluid dynamics model of aortic coarctation partially validates against real MRI-derived geometry, though differences in maximal pressure and wall shear stress highlight the need for patient-specific geometric parameters.
Peak discrepancies advise against direct clinical use; leaves open validation of patient-specific geometry in coarctation CFD models.
In this work, we first investigated the hemodynamic parameters in the case of a normal aortic arch anatomy and in the case of aortic coarctation anatomy, both generated by using CFX-ICEM-ANSYS simulations. Then, we compared these results with those obtained for a proposed model without and with aortic coarctation, while introducing a real tridimensional magnetic resonance imaging geometry in the simulation process. The conclusion is that our proposed model reproduces, with a high agreement, the real case obtained from imaging data.
