Figure 4

3D stream-lines representing vascular hemodynamics in a 37 year-old male 35 years after surgical repair of aortic coarctation. Note the flow acceleration through the tubular shaped transverse arch inducing a flow jet into the aneurysm and circumferential separation and recirculation of the inflowing streamlines which develop into an umbrella-like blood flow pattern. A = lateral view, B = cranial view, C = posterior view. A more detailed depiction of the temporal evolution of 3D blood flow is provided in the additional file 2.
