RISA Predictive Analysis of Wall Stress in Abdominal Aortic Aneurysms Using a Neural Network Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rupture risk assessment of abdominal aortic aneurysms (AAAs) by means of quantifying wall stress is a common biomechanical strategy. However, the clinical translation of this approach has been greatly limited due to the ...
Numerical Simulation of Particle Transport and Deposition in the Pulmonary Vasculature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To quantify the transport and adhesion of drug particles in a complex vascular environment, computational fluid particle dynamics (CFPD) simulations of blood flow and drug particulate were conducted in three different ...
A Hemodynamic Comparison of Myocardial Bridging and Coronary Atherosclerotic Stenosis: A Computational Model With Experimental Evaluation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Myocardial bridging (MB) and coronary atherosclerotic stenosis can impair coronary blood flow and may cause myocardial ischemia or even heart attack. It remains unclear how MB and stenosis are similar or different regarding ...
The Importance of Patient Specific Regionally Varying Wall Thickness in Abdominal Aortic Aneurysm Biomechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abdominal aortic aneurysm (AAA) is a vascular condition where the use of a biomechanicsbased assessment for patientspecific risk assessment is a promising approach for clinical management of the disease. Among various ...
Effects of Intraluminal Thrombus on Patient Specific Abdominal Aortic Aneurysm Hemodynamics via Stereoscopic Particle Image Velocity and Computational Fluid Dynamics Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pathology of the human abdominal aortic aneurysm (AAA) and its relationship to the later complication of intraluminal thrombus (ILT) formation remains unclear. The hemodynamics in the diseased abdominal aorta are ...
The Relationship Between Surface Curvature and Abdominal Aortic Aneurysm Wall Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The maximum diameter (MD) criterion is the most important factor when predicting risk of rupture of abdominal aortic aneurysms (AAAs). An elevated wall stress has also been linked to a high risk of aneurysm rupture, yet ...
A Protocol for Measuring Pull off Stress of Wound Treatment Polymers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Skin wounds and burns compromise the body's natural barrier to bacteria and other pathogens. While many forms of wound dressings are available, polymeric films are advantageous for various reasons, ranging from the ease ...
Abdominal Aortic Aneurysm: From Clinical Imaging to Realistic Replicas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this work is to develop a framework for manufacturing nonuniform wall thickness replicas of abdominal aortic aneurysms (AAAs). The methodology was based on the use of computed tomography (CT) images for virtual ...
A Methodology for Verifying Abdominal Aortic Aneurysm Wall Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An abdominal aortic aneurysm (AAA) is a permanent focal dilatation of the abdominal aorta of at least 1.5 times its normal diameter. Although the criterion of maximum diameter is still used in clinical practice to decide ...
A Methodology for the Derivation of Unloaded Abdominal Aortic Aneurysm Geometry With Experimental Validation
