Certain investigations on prediction of dissected aorta using computational fluid dynamic analysis Available to Purchase

Nowadays, Aortic Dissection is unpredictable endangering disease, which initiates injury in the body structure of aortic layers, and false lumen is created due to avulsion. In our human system, blood flows through the false lumen that protrudes in the heart’s aorta, and it leads to an intimal flap. Aortic dissection is the primary cause of morbidity and mortality in cardiac patients. If Aortic Dissection is untreated, 33% of patients die within 24 hours from diagnosis, 50% in 48 hours, 75% death happens within two-week time, and 90% in one month of a timeline. The surgical procedure is available to replace dissected aorta - Type A using prosthesis. For Dissected Aorta-Type B is substituted using a stent-grafts. 3D model for a Stanford type A dissected aorta is designed by importing Computer Tomography images in DICOM format by MIMICS tool (Materialize Interactive Medical Image Control System). The entries and re-entries count of blood vessels is measured, and the lumen area, a diameter of the lumen, is calculated in the 3D segmented aorta in the MIMICS tool. The centreline calculation in the MIMICS tool gives exhaustive details about the transport of blood inside the true and false lumen. Also, it helps to predict the bulging of the aorta. Various loads are applied on the designed 3D model, and parameters like shear stress and Von shear strain are interrupted using ANSYS software.
