From: Assessment of energy loss across aortic valves using accelerated CMR multi-point flow measurements
Complex flow patterns during systole in the ascending aorta of two patients, a) with a diseased aortic valve, and b) with a CoreValve implanted 2 years before measurement. The colors of the streamlines correspond to velocities, and the isosurfaces to different levels of TKE. Because of the signal void inside the CoreValve (b) only the distal part of the flow is displayed.
