1. A method for assessing heart valve operation with medical diagnostic imaging data, the method comprising: automatically determining, by a processor, a first location of a heart valve from application of the medical diagnostic imaging data to a global location model, the first location being determined as a global heart valve position of the overall heart valve within a volume represented by the medical diagnostic imaging data; determining, by the processor, a second location of an anatomical landmark of the heart valve relative to the heart valve, the determining of the second location being a function of the determined first location of the global heart valve position; determining, by the processor, a surface of the heart valve as a function of the determined second location of the landmark, the surface representing a geometry of the heart valve itself; and displaying an image representing the heart valve, the image being a function of the surface.
