From: Phase contrast 4D flow in bicuspid aortic valves in a porcine model
Postoperative streamline analysis of pig 1 after bicuspidalization with right-left aortic leaflet fusion. In (a) there is a right-handed helical flow in the ascending aorta and the distal aortic arch (arrows). In (b) vortices are extracted from the image data. A big vortex can be visualized in the aortic arch, a small vortex in the ascending aorta.
