RISInfarcted Left Ventricles Have Stiffer Material Properties and Lower Stiffness Variation: Three Dimensional Echo Based Modeling to Quantify In Vivo Ventricle Material Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Methods to quantify ventricle material properties noninvasively using in vivo data are of great important in clinical applications. An ultrasound echobased computational modeling approach was proposed to quantify left ...
Effects of Residual Stress, Axial Stretch, and Circumferential Shrinkage on Coronary Plaque Stress and Strain Calculations: A Modeling Study Using IVUS-Based Near-Idealized Geometries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate stress and strain calculations are important for plaque progression and vulnerability assessment. Models based on in vivo data often need to form geometries with zero-stress/strain conditions. The goal of this ...
Combining IVUS and Optical Coherence Tomography for More Accurate Coronary Cap Thickness Quantification and Stress/Strain Calculations: A Patient-Specific Three-Dimensional Fluid-Structure Interaction Modeling Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate cap thickness and stress/strain quantifications are of fundamental importance for vulnerable plaque research. Virtual histology intravascular ultrasound (VH-IVUS) sets cap thickness to zero when cap is under ...
Optical Coherence Tomography-Based Patient-Specific Residual Multi-Thrombus Coronary Plaque Models With Fluid–Structure Interaction for Better Treatment Decisions: A Biomechanical Modeling Case Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Intracoronary thrombus from plaque erosion could cause fatal acute coronary syndrome (ACS). A conservative antithrombotic therapy has been proposed to treat ACS patients in lieu of stenting. It is speculated that the ...
