Computational Analysis of Turbulent Hemodynamics in Radiocephalic Arteriovenous Fistulas to Determine the Best Anastomotic Angles

Alfio Quarteroni, Christian Vergara

Background: Hemodynamics has been known to play a major role in the development of intimal hyperplasia leading to arteriovenous fistula failure. The goal of our study is to investigate the influence of different angles of side-to-end radiocephalic anastomo ...

Multi-time-lag PIV analysis of steady and pulsatile flows in a sidewall aneurysm

Mohamed Farhat, Pierre Bouillot

The effect of inflow waveform on the hemodynamics of a real-size idealized sidewall intracranial aneurysm (IA) model was investigated using particle imaging velocimetry (PIV). For this purpose, we implemented an error analysis based on several PIV measurem ...

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

Nikolaos Stergiopoulos, Philippe Reymond, François Lazeyras

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 ...

Validation of a patient-specific one-dimensional model of the systemic arterial tree

Nikolaos Stergiopoulos, Philippe Reymond, Yvette Bohraus, François Lazeyras

Reymond P, Bohraus Y, Perren F, Lazeyras F, Stergiopulos N. Validation of a patient-specific one-dimensional model of the systemic arterial tree. Am J Physiol Heart Circ Physiol 301: H1173-H1182, 2011. First published May 27, 2011; doi:10.1152/ajpheart.008 ...

Validation of a one-dimensional model of the systemic arterial tree

Nikolaos Stergiopoulos, Fabrice Merenda, Philippe Reymond

A distributed model of the human arterial tree including all main systemic arteries coupled to a heart model is developed. The one-dimensional (1-D) form of the momentum and continuity equations is solved numerically to obtain pressures and flows throughou ...

On parallel computation of blood flow in human arterial network based on 1-D modelling

Alfio Quarteroni, Luca Formaggia

Parallel computation of blood flow in a 1D model of human arterial network has been carried out employing a Taylor Galerkin finite element method. Message passing interface libraries have been used on Origin 2000 SGI machine. A Greedy strategy for load-dis ...

Determinants of stroke volume and systolic and diastolic aortic pressure

Nikolaos Stergiopoulos, Jean-Jacques Meister, Nico Westerhof

We investigated how parameters describing the heart and the arterial system contribute to the systolic and diastolic pressures (Ps and Pd, respectively) and stroke volume (SV). We have described the heart by the varying-elastance model with six parameters ...
