Numerical Modeling of Stress in Stenotic Arteries With Microcalcifications: A Parameter Sensitivity Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a follow-up to the work presented in (2010, “Numerical Modeling of Stress in Stenotic Arteries With Microcalcifications: A Micromechanical Approximation,” ASME J. Biomech. Eng., 132, p. 091011), ...
Numerical Modeling of Stress in Stenotic Arteries With Microcalcifications: A Micromechanical Approximation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Most finite element models of atherosclerotic arteries do not account for the heterogeneity of the plaque constituents at the microscale. Failure of plaque lesions has been shown to be a local ...
A Method for Automatically Optimizing Medical Devices for Treating Heart Failure: Designing Polymeric Injection Patterns
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heart failure continues to present a significant medical and economic burden throughout the developed world. Novel treatments involving the injection of polymeric materials into the myocardium of ...
Simulation of Mechanical Environment in Active Lead Fixation: Effect of Fixation Helix Size
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The risk of myocardial penetration due to active-fixation screw-in type pacing leads has been reported to increase as the helix electrodes become smaller. In order to understand the contributing ...
Regional Left Ventricular Myocardial Contractility and Stress in a Finite Element Model of Posterobasal Myocardial Infarction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, a noninvasive method for determining regional myocardial contractility, using an animal-specific finite element (FE) model-based optimization, was developed to study a sheep with anteroapical ...
A Novel Method for Quantifying In-Vivo Regional Left Ventricular Myocardial Contractility in the Border Zone of a Myocardial Infarction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Homogeneous contractility is usually assigned to the remote region, border zone (BZ), and the infarct in existing infarcted left ventricle (LV) mathematical models. Within the LV, the contractile ...
