Fluidodinâmica Computacional na Avaliação do Risco Futuro de Aneurismas de Aorta Ascendente

Abstract: Resumo Fundamentos Uma metodologia para identificação de pacientes portadores de aneurisma de aorta ascendente (AAAs) sob alto risco de remodelamento aórtico não está completamente definida. Objetivo Esta pesquisa objetiva caracterizar numericamente o fluxo sanguíneo aórtico, relacionando a distribuição do estresse mecânico resultante com o crescimento de AAAs. Métodos Estudo analítico, observacional, unicêntrico, em que um proto… Show more

“…Pixel size and slice thickness data were used for the reconstruction of the 3D model of the aorta to its actual size. As a final procedure to create the computational domain, allowing a comparison of the results of two exams of the same patient, a geometry overlapping was employed [ 26 ] ( Figure 2 b). This ensured the consistent positioning of the inlet valve, provided a common coordinate system, and allowed the definition of the same region of interest ( Figure 2 c) to compare their volumes.…”

“…The angle was defined as the distance between the aortic annulus plane and the line connecting the brachiocephalic trunk centroid with the left main coronary artery centroid ( Figure 2 d). Further details can be found in Almeida et al [ 26 ].…”
