Blood velocity and pressure fields in large arteries are greatly influenced by the deformability of the vessel. We have developed a Coupled Momentum Method to simulate blood flow in three-dimensional deformable models of arteries. The animation belows shows the application of the method to a patient-specific model of the thoracic aorta of a young patient with severe aortic coarctation.
