Maximum aortic diameter has been the mainstay metric for aortic disease management and surgical intervention for decades, specifically acute aortic dissection and aneurysm. While this size metric has been effective at separating patient populations into groupings associated with required intervention and monitoring for eventual intervention respectively, size alone ignores the role of complex geometric shape and how it may be further indicative of disease state. Analyses of aortic shape in addition to size have been discussed at length in literature, however the representations and methods to convey shape are siloed and often highly subjective. Machine learning methodologies offer a means to explore high dimensional feature spaces and can identify a sparse set of metrics which result in a division of patient responses parametrized by physical and interpretable variables. Additionally, by introducing a modeling workflow which contains engineered parameters designed to describe aortic shape, in addition to traditional size metrics, the exploration of shape dependence on intervention outcomes becomes more comprehensive across size-shape parameter spaces. The engineered parameters presented primarily incorporate estimations of integrated Gaussian surface curvature into features that contain both the magnitude and spatial variation in shape of the aortas. The models discussed accurately classify over two hundred aortic disease patients spanning aneurysm, dissection, and other modalities with accuracies above 90% and performance across multiple modeling methodologies is discussed. The classification success of the geometrically informed feature space suggests the underlying dependence on pathology shape on the success of the intervention outcome. The most clinically effective models will preserve the wealth of information in modern medical diagnostics and imaging into descriptive, and physically interpretable, parameters to aid in clinical decision making.
