Haemodynamic analysis of a patient-specific aortic arch geometry using 4D-MRI and computational fluid dynamics in a coupled 3D-0D framework

Regions of the aortic arch affected by an aneurysm or dissection may require surgical intervention using vascular grafts, which includes a means of re-perfusing the supra-aortic branch vessels, comprised of the left subclavian artery (LSA), left common carotid artery (LCCA) and innominateartery. During open surgical repair, it is crucial that the chosengraft configuration promotes physiological perfusion, to prevent ischaemic neurologic and cardiac events. It is clear, therefore, that enhanced understanding of perfusion in patient-specific cases is critical to improving clinical practice andpatient outcomes.
