1. A computer-implemented method of identifying a personalized cardiovascular device based on patient-specific geometrical information, the method comprising: acquiring a geometric model of at least a portion of a patient's vascular system; obtaining one or more geometric quantities of one or more blood vessels of the patient's vascular system; determining the presence of a pathology characteristic at a location of the patient's vascular system represented in the geometric model based on the one or more obtained geometric quantities; defining one or more geometric design variables of a personalized cardiovascular device to treat the pathology characteristic; generating an objective function defined by the one or more geometric design variables and hemodynamic or solid mechanics performance characteristics of the personalized cardiovascular device; modifying the geometric model by iteratively updating one or more of the geometric design variables of the personalized cardiovascular device and modeled deployment of the iteratively updated personalized cardiovascular device in the geometric model; and optimizing the objective function to identify a plurality of values of the one or more geometric design variables that result in desired hemodynamic or solid mechanics performance characteristics of the personalized cardiovascular device based on the iteratively updated geometric design variables.
