RISA Characteristic Based Constitutive Law for Dispersed Fibers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Biological tissues are typically constituted of dispersed fibers. Modeling the constitutive laws of such tissues remains a challenge. Direct integration over all fibers is considered to be accurate but requires very expensive ...
Finite Element Modeling of Mitral Valve Repair
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mitral valve is a complex structure regulating forward flow of blood between the left atrium and left ventricle (LV). Multiple disease processes can affect its proper function, and when these diseases cause severe ...
A Novel Method for Quantifying Smooth Regional Variations in Myocardial Contractility Within an Infarcted Human Left Ventricle Based on Delay Enhanced Magnetic Resonance Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heart failure is increasing at an alarming rate, making it a worldwide epidemic. As the population ages and life expectancy increases, this trend is not likely to change. Myocardial infarction (MI)induced adverse left ...
In Vivo Quantification of Ascending Thoracic Aortic Aneurysm Wall Stretch Using MRI: Relationship to Repair Threshold Diameter and Ex Vivo Wall Failure Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ascending thoracic aortic aneurysms (aTAAs) can lead to life-threatening dissection and rupture. Recent studies have highlighted aTAA mechanical properties as relevant factors associated with progression. The aim of this ...
