Pulsatile Flow Investigation in Development of Thoracic Aortic Aneurysm: An In-Vitro Validated Fluid Structure Interaction Analysis.

Thoracic aortic aneurysm (TAA) is a severe cardiovascular disease with a high mortality rate, if left untreated... ...In order to gain more insight on TAA formation, we developed a computational framework in vitro to investigate and compare the flow patterns between pre-aneurismal and post-aneurismal aorta using a deformable wall model... ...The pulsatile flow was created using a piston pump (SuperPump AR series, ViVitro Labs Inc., Victoria, BC, Canada) generating the inlet velocity profile with the How rate of 4 L/min at the frequency of 1 Hz, extracted from the literature …
