ABSTRACT:
Patient-specific multiscale fluid-structure interaction (FSI) models are becoming the gold standard approach for validating the performances of biomedical devices and assessing haemodynamic risk in healthy and pathological conditions. The performances of the biological prostheses commonly adopted in the surgical replacement of a diseased aortic valve are compared in terms of mechanical stresses induced by blood within the aortic root wall. To do this aim, a computational study is discussed in terms of FSI simulations in patient-specific geometries. The same methodologies are also adopted to the problem of predictive haemodynamic risk quantification in aneurysms by proposing two new risk indicators based on the recent Three-Band Decomposition analysis applied to the Wall Shear Stress signal. A detailed comparison is conducted with respect to the most common risk indices adopted in the Literature. Finally, the correct definition of the Wall Shear Stress Spatial Gradient is formulated by using the mathematical instruments provided by differential geometry.
