An abdominal aortic aneurysm (AAA) causes the wall of a person’s aorta, the largest artery in the body, to weaken and bulge outward. Predicting the risk of AAA rupture involves a combination of imaging studies, such as ultrasound, CT scans, and MRI, and hemodynamics, as well as clinical factors such as age, sex, smoking history, and family history of AAA. To solve the blood flow governing equations under the pulsating conditions caused by the heart’s beating, they used finite element-based simulations. The team found that aneurysm size alters the blood flow velocity distribution. “In the future, such computational work will help in the development of digital twins of the cardiovascular system,” said Kumar.
