1. A method for non-invasive hemodynamic assessment of aortic coarctation, comprising: estimating patient-specific lumen anatomy of an aorta and supra-aortic arteries from medical image data of a patient; estimating patient-specific aortic blood flow rates from the medical image data of the patient; calculating patient-specific inlet and outlet boundary conditions for a computational model of aortic blood flow based on the patient-specific lumen anatomy, the patient-specific aortic blood flow rates, and non-invasive clinical measurements of the patient; and computing aortic blood flow and pressure over the patient-specific lumen anatomy using the computational model of aortic blood flow and the patient-specific inlet and outlet boundary conditions.
