Physiological simulation of blood flow in the aorta: comparison of hemodynamic indices as predicted by 3-D FSI, 3-D rigid wall and 1-D models

Alfio Quarteroni, Nikolaos Stergiopoulos, Simone Deparis, Philippe Reymond, Paolo Crosetto

Interest in patient-specific blood-flow circulation modeling has increased substantially in recent years. The availability of clinical data for geometric and elastic properties together with efficient numerical methods has now made model rendering feasible ...

Patient-specific mean pressure drop in the systemic arterial tree, a comparison between 1-D and 3-D models

Nikolaos Stergiopoulos, François Lazeyras, Philippe Reymond

One-dimensional models of the systemic arterial tree are useful tools for studying wave propagation phenomena, however, their formulation for frictional losses is approximate and often based on solutions for developed flow in straight non-tapered arterial ...

A method for the quantification of the pressure dependent 3D collagen configuration in the arterial adventitia

Nikolaos Stergiopoulos, Jelle Tymen Christiaan Schrauwen

Collagen plays an important role in the response of the arterial wall to mechanical loading and presumably has a load-bearing function preventing overdistension. Collagen configuration is important for understanding this role, in particular in mathematical ...

A two-level time step technique for the partitioned solution of one-dimensional arterial networks

Simone Deparis, Adelmo Cristiano Innocenza Malossi

In this work a numerical strategy to address the solution of the blood flow in one-dimensional arterial networks through a topology-based decomposition is presented. Such decomposition results in the local analysis of the blood flow in simple arterial segm ...

Identification and Functional Response of "Interstitial Cells of Cajal"-like Cells from Rat Mesenteric Artery

Aurélie Formey de Saint Louvent

This thesis is a contribution to the field of interstitial cells of Cajal-like cells (ICC-LCs) in the vasculature. Indeed, cells with irregular shapes and numerous long thin filaments, morphologically similar to the gastrointestinal ICCs, have been observe ...

Pressure and Flow Wave Propagation in Patient-Specific Models of the Arterial Tree

Philippe Reymond

Blood flow in the arterial circulation induces hemodynamic forces that play an important role in various forms of vascular diseases. Temporal variation of the wall shear stress seems to play a significant role in atherogenesis and plaque stability. Flow in ...

Identification and functional response of interstitial Cajal-like cells from rat mesenteric artery

Jean-Jacques Meister, Jean-Louis Bény, Lara Buscemi Estefanell, Aurélie Formey de Saint Louvent

Cells with irregular shapes, numerous long thin filaments, and morphological similarities to the gastrointestinal interstitial cells of Cajal (ICCs) have been observed in the wall of some blood vessels. These ICC-like cells (ICC-LCs) do not correspond to t ...
