Full textThe results of the surgical repair of aortic coarctation are excellent. Beside these successes, patients who underwent a coarctation repair in infancy remain at high risk for resting hypertension in later life. This hypertension is responsible for an increased mortality mostly related to cardiovascular events. Screening for hypertension and its risk factors is the main objective of the follow-up. The present work, using modern non invasive imaging techniques, allowed characterizing an arterial phenotype associated with a high risk of hypertension in patients who had undergone coarctation surgery. In this setting, a novel method for calculating pulse wave velocity with using MRI was developed and used to evaluate the mechanical and biophysical properties of the aorta. MRI flow mapping was also used to analyze fluids dynamics in the aorta and to extract haemodynamic parameters. Thus, we have identified anatomical and functional markers of the aorta which are independent predictor of hypertension in post-coarctectomy patients. Indeed, in a given patient, the co-existence of both abnormality of the aortic arch shape and impairment of vascular function confers a high risk for hypertension. Our results are of importance in both preventive and curative strategies

Full textDrug-eluting stents (DES), which release anti-proliferative drugs into the arterial wall in a controlled manner, have drastically reduced the rate of in-stent restenosis and revolutionized the treatment of atherosclerosis. However, late stent thrombosis remains a safety concern of DES, mainly due to delayed healing of the wound inflicted during DES implantation. We present a framework to optimize DES design such that restenosis is inhibited without affecting the healing process. To this end, we have developed a computational model of blood flow and drug transport in stented arteries which provides a metric for quantifying DES performance. The model takes into account the multi-layered structure of the arterial wall and incorporates a reversible binding model to describe drug interaction with the cells of the arterial wall. The model is coupled to a novel optimization algorithm that minimizes the DES performance metric to identify optimal DES designs. We show that optimizing the period of drug release from DES and the initial drug concentration within the coating has a drastic effect on DES performance. Optimal paclitaxel-eluting stents release the drug either within a few hours or slowly within a year at concentrations considerably lower than current DES. Optimal sirolimus-eluting stents require a slow drug release. Optimal strut shapes for DES are elongated and can be streamlined only if the drug release occurs quickly. The results offer explanations for the performance of recent DES designs, demonstrate the potential for large improvements in DES design relative to the current state of commercial devices, and define guidelines for implementing these improvements

Full textThis thesis is based on identifying the mechanical properties of facial arteries. It is part of FlowFace project, which focuses on the study of the facial arterial system by MRI imaging. It is based on a measurement campaign conducted on a sample of 30 people at the Hospital of Amiens, which allowed obtaining noninvasively the evolution of the blood vessel deformation and the measurement of the flow. Diastolic and systolic pressures were measured at the arm independently of the MRI measurements. The aim of the thesis was to model the deformation of blood vessels and to implement an optimization technique to determine their mechanical properties by inverse analysis using MRI measurements of deformation. Simulations of the behavior of the blood vessels were performed, using ANSYS Inc. software, modeling fluid-structure interactions both strong and weak coupling. The objective was to determine the parietal deformations induced by hemodynamic conditions and pressure drops in the vessels concerned. The simulations involved hyperelastic and large deflection models to simulate the behavior of the wall. They allow calculate the numerical displacements that we compared with experimental displacements measured by MRI, the aim is that the difference between numerical and experimental be as low as possible to deduce the adequate mechanical parameters for the artery. To identify the mechanical properties of the vessels, the optimization technique proposed in ANSYS based on genetic algorithms or gradient algorithms was used. The identification method was validated on cylindrical tubes (elastomer), for which deformation measurements were acquired by MRI imaging under pulsating flow. The values of mechanical properties determined were compared with those obtained by traction tests and dilatation tests. One of the crucial points of identification involves the determination of the non-stress state. If it is a known parameter for the elastic tube, it has to be determining for blood vessels. The challenge of this thesis is to determine from a "minimum" quantity of pressure and deformation information, the hyper-elastic properties of blood vessels. The method based on a patient-specific geometry deformation concluded that the tangent modulus in diastole is approximately 200kPa while that in systole is in a range of 300 kPa to 1 MPa

Full textOur contribution concerns the following three complementary domains : Automatic Differentiation, op- timal shape design for large systems, mesh adaption. In the chapter 1 of the part 1, we expose a method to compute gradients using Automatic Differentiation for a classical optimal shape design problem. We exply how to deduce an exact gradient based on an adjoint state without storing explicitly the Jacobian matrix. The reverse mode of the DA that we propose use much legs memory storage. In the chapter 2 of the part 2, we propose a SQP-like method to solve a class of optimization problems with equality constraints. We use a low cost iteration to solve the state and the adjoint. The new algorithm enables to solve simultaneously the optimality system. This one shot method combines efficiency and robustness. In the chapter 3 of the part 2, we study a new preconditioning strategy for optimal shape design. We build an additive multilevel preconditioning starting from the classical Bramble-Pasciak-Xu principle and from the agglomeration principle. We specify easily the gain of regularity of our preconditioning using only one real parameter. In the chapter 1 of the part 3, we study the problem of the best adapted mesh for a pure interpolation problem. We specify the mesh with a metric and we model the interpolation error. The optimality system solution gives a completely explicite expression of the optimal metric as a function of the function to adapt. In the chapter 2 of the part 3, we extend the method of the previous chapter to the problem of mesh adaption for P. D. E. Our method is based on a rigourous a priori analysis followed by a modelization. We obtain an optimal control formulation with an adjoint state
