Time-resolved 3D particle traces in patient 1, 13 years after operative repair of aortic coarctation by a Waldhausen subclavian flap angioplasty. The movie illustrates the temporal evolution of blood flow originating from emitter planes in the ascending aorta and aortic arch. Three distinct flow patterns can clearly be appreciated: Accelerated flow in the tubular shaped aortic arch, vortex formation within the descending aortic aneurysm, and considerable helical flow in the ascending and descending aorta. Color coding = local blood flow velocity magnitude.

Time-resolved particle traces in patient 2, 35 years after coarctation repair by Vossschulte approach. Clearly, the increased velocities in the hypoplastic aortic arch can be appreciated. The blood flow is accelerated towards the opposite wall of the eccentric aneurysm, presents a circumferential separation and recirculation of the inflowing streamlines and is redirected in all directions in an umbrella-like fashion.
