Time course of flow-induced adaptation of carotid artery biomechanical properties, structure and zero-stress state in the arteriovenous shunt

Numerous studies have provided evidence of diameter adaptation secondary to flow-overload. but with ambiguous findings vis a vis other morphological parameters and information on the biomechanical aspects of arterial adaptation is rather incomplete. We exa ...

Symbios SPS-standard and custom stem micromotion comparison by micro- CT imaging

Vu Thanh-Hieu Nguyen

The aim of this study is to compare the difference in µ-motion between a custom stem implant and a sps standard stem and assess the importance of patient specificity. A surgeon would implant 3 sps-standar stems and 3 custom stems in 6 cadaveric femurs. The ...

Numerical validation of a new method to assess aortic pulse wave velocity from a single recording of a brachial artery waveform with an occluding cuff

Nikolaos Stergiopoulos, Philippe Reymond, Bram Trachet, Patrick Segers

Recently a new method has been proposed as a tool to measure arterial pulse wave velocity (PWV), a measure of the stiffness of the large arteries and an emerging parameter used as indicator of clinical cardiovascular risk. The method is based on measuremen ...

A fluid mechanical view on Abdominal Aortic Aneurysms

François Gallaire

Abstract * Article Structure * Figures and Tables * References Abdominal aortic aneurysms are a dilatation of the aorta, localized preferentially above the bifurcation of the iliac arteries, which increases in time. Understanding their localization and g ...

Initial In Vivo Studies with a Polymer-based MR-compatible Guide Wire

The purpose of this study was to evaluate a new polymer-based and magnetic resonance (MR) imaging-compatible guide wire for its application in MR-guided endovascular interventions, particularly for interventional peripheral MR angiography in swine experime ...

A numerical solution of a one-dimensional blood flow model - moving grid approach

Vincent Gajdosik

We consider a one-dimensional blood flow model suitable for larger arteries. It consists of a hyperbolic system of two coupled nonlinear equations. The model has already been successfully used in practice. Its numerical solution is usually achieved by mean ...

Effect of elastin degradation on carotid wall mechanics as assessed by a constituent-based biomechanical model

Nikolaos Stergiopoulos, Sylvain Roy, Luca Augsburger, Edouard Fonck, Gilles Prod'Hom

Arteries display a nonlinear anisotropic behavior dictated by the elastic properties and structural arrangement of its main constituents, elastin, collagen, and vascular smooth muscle. Elastin provides for structural integrity and for the compliance of the ...

Heterogeneous domain decomposition methods for fluid-structure interaction problems

Alfio Quarteroni, Simone Deparis, Gilles Fourestey, Marco Discacciati

In this note, we propose Steklov-Poincaré iterative algorithms (mutuated from the analogy with heterogeneous domain decomposition) to solve fluidstructure interaction problems. Although our framework is very general, the driving application is concerned wi ...

Effects of arterial wall stress on vasomotion

Jean-Jacques Meister, Roger Sauser, Jean-Louis Bény, Michèle Koenigsberger

Smooth muscle and endothelial cells in the arterial wall are exposed to mechanical stress. Indeed blood flow induces intraluminal pressure variations and shear stress. An increase in pressure may induce a vessel contraction, a phenomenon known as the myoge ...
