Multicomponent Mechanical Characterization of Atherosclerotic Human Coronary Arteries
An Experimental and Computational Hybrid Approach
Atherosclerotic plaque rupture in coronary arteries, an important trigger of myocardial infarction, is shown to correlate with high levels of pressure-induced mechanical stresses in plaques. Finite element (FE) analyses are commonly used for plaque stress assessment. However, ...
A Framework for Local Mechanical Characterization of Atherosclerotic Plaques
Combination of Ultrasound Displacement Imaging and Inverse Finite Element Analysis
Biomechanical models have the potential to predict plaque rupture. For reliable models, correct material properties of plaque components are a prerequisite. This study presents a new technique, where high resolution ultrasound displacement imaging and inverse finite element (F ...
A tissue-engineered model of the atherosclerotic plaque cap
Toward understanding the role of microcalcifications in plaque rupture
Rupture of the cap of an atherosclerotic plaque can lead to thrombotic cardiovascular events. It has been suggested, through computational models, that the presence of microcalcifications in the atherosclerotic cap can increase the risk of cap rupture. However, the experimenta ...

A Twelve-Metric Sensitivity Study using Plaque-Specific Fibre Architectures
increased thickness of the intima layer of an artery, due to build-up of, among
others, lipid deposits. Eventually, this could cause rupture of the blood vessel’s
wall, leading to thromb ...
Ischemic stroke is a major cause of death worldwide. Atherosclerosis in the carotid arteries is an established predictor of these events. FSI shows its advantage in simulating the hemodynamic environments due to involving the multiphysics coupling of fluid dynami ...
