Computational fluid dynamics simulation of transcatheter aortic valve degeneration.
OBJECTIVES Studied under clinical trials, transcatheter aortic valves (TAV) have demonstrated good short-term feasibility and results in high-risk surgical patients with severe aortic stenosis. However, their long-term safety and durability are unknown. The objective of this study is to evaluate hemodynamic changes within TAV created by bioprosthetic leaflet degeneration. METHODS Computationa...
متن کاملComputational fluid dynamic simulations for determination of ventricular workload in aortic arch obstructions.
OBJECTIVE The cardiac workload associated with various types of aortic obstruction was determined using computational fluid dynamic simulations. METHODS Computed tomography image data were collected from 4 patients with 4 distinct types of aortic arch obstructions and 4 controls. The categorization of arch hypoplasia corresponded to the "A, B, C" nomenclature of arch interruption; a type "D" ...
متن کاملHydrodynamic Improvement of underwater glider by Computational Fluid Dynamics method
Gliders are new marine vehicles which have research and military uses and they move by sequent diving and climbing. Suitable design of its main body and wings are important for the most advance velocity. hydrodynamic design variables are main body form, wings (cross section, dimensions, shape, longitudinal and vertical position) and hydrostatic parameters (static trim angle, amount of added for...
متن کاملPatient-specific computational fluid dynamics-assessment of aortic hemodynamics in a spectrum of aortic valve pathologies.
OBJECTIVES The complexity of aortic disease is not fully exposed by aortic dimensions alone, and morbidity or mortality can occur before intervention thresholds are met. Patient-specific computational fluid dynamics (CFD) were used to assess the effect of different aortic valve morphologies on velocity profiles, flow patterns, helicity, wall shear stress (WSS), and oscillatory shear index (OSI)...
متن کاملIncluding aortic valve morphology in computational fluid dynamics simulations: initial findings and application to aortic coarctation.
Computational fluid dynamics (CFD) simulations quantifying thoracic aortic flow patterns have not included disturbances from the aortic valve (AoV). 80% of patients with aortic coarctation (CoA) have a bicuspid aortic valve (BAV) which may cause adverse flow patterns contributing to morbidity. Our objectives were to develop a method to account for the AoV in CFD simulations, and quantify its im...
