Fig 1 Oblique sagittal retrospectively gated steady-state free precession magnetic resonance imaging sequences image of a 12-year-old patient with discrete coarctation. The flow measurement plane is placed orthogonally to the blood flow at each location in the descending aorta: at the coarctation site, at the diaphragm, and halfway between both sites.

Fig 2 Mean flow volumes at three locations in the descending aorta of coarctation patients (squares) and control patients (triangles): proximal, at the coarctation or juxtaductal site; distal, at the diaphragm; and midpoint, halfway between proximal and distal sites.
