RISFluid Structure Interaction Model of Aortic Valve With Porcine Specific Collagen Fiber Alignment in the Cusps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Native aortic valve cusps are composed of collagen fibers embedded in their layers. Each valve cusp has its own distinctive fiber alignment with varying orientations and sizes of its fiber bundles. However, prior mechanical ...
A New Growth Model for Aortic Valve Calcification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Calcific aortic valve disease (CAVD) is a progressive disease in which minerals accumulate in the tissue of the aortic valve cusps, stiffening them and preventing valve opening and closing. The process of valve calcification ...
Comparative Fluid–Structure Interaction Analysis of Polymeric Transcatheter and Surgical Aortic Valves' Hemodynamics and Structural Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Transcatheter aortic valve replacement (TAVR) has emerged as an effective alternative to conventional surgical aortic valve replacement (SAVR) in high-risk elderly patients with calcified aortic valve disease. All currently ...
Fluid–Structure Interaction Models of Bicuspid Aortic Valves: The Effects of Nonfused Cusp Angles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bicuspid aortic valve (BAV) is the most common type of congenital heart disease, occurring in 0.5–2% of the population, where the valve has only two rather than the three normal cusps. Valvular pathologies, such as aortic ...
