Case 2: Dilatation of the ascending and coarctation of the descending aorta

4D flow aorta: Dilated ascending aorta with an eccentric flow towards the right border of the aorta and vortex formation on the left side. Coarctation of the descending aorta with flow acceleration through the stenosis. Aortic 4D flow-map at late systole: Pathlines demonstrates eccentric flow hitting the right wall of ascending aorta (yellow arrow) and vortex formation on the opposite side (white arrow). Flow acceleration is seen in the coarctation (red arrow).
