Surgically repaired coarctation of the aorta (flow model)

thingiverse

This is a patient-specific blood flow model designed to investigate the efficacy of surgical repair for a disease of the aorta called coarctation of the aorta (or 'COA'). The model includes the aorta, supra-aortic branch vessels, and fittings to incorporate the tubing needed to deliver a blood mimicking fluid. Also included are post-processed images of a 3D magnetic resonance imaging (MRI) exam which measures blood flow through the repaired section of the aorta (both 'in-vivo', i.e. in the patient and 'in-vitro' i.e. in the flow model). The repaired section is indicated by arrows showing where the coarctation previously existed. For more details regarding the imaging and patient demographics please refer to the case-study below: Bradley D. Allen, Alex J. Barker, James C. Carr, Robert A.

Rafts and infill will obstruct the lumen of the vessel. Post-Printing 4D flow MRI of the original patient which shows complex blood flow due to the presence of a bicuspid aortic valve and coarctation of the aorta. Patient specific aorta model printed from the MRI data shown above. Comparison of in-vivo MRI measurements with in-vitro flow model
