Limitations of temporal and spatial resolution prevent MRI from visualizing boundary layers and fluid structure interaction (FSI) occurring immediately adjacent to the valve leaflets as well as at the aortic wall downstream from the valve. We make use of CMR image-based patient specific anatomy and boundary conditions to perform computational fluid dynamic (CFD) analysis which incorporates moving boundary conditions. The numerical approach is shown to elucidate complex and dynamic blood and leaflet behavior previously not seen with CMR alone.
