Fig. 5From: Altered hemodynamics by 4D flow cardiovascular magnetic resonance predict exercise intolerance in repaired coarctation of the aorta: an in vitro studyRepresentative aortas of patients with poor (left) and excellent (right) exercise capacity (VO2 max) during simulated rest (top) and exercise (bottom). Visualizations of streamline flow, vorticity, and helicity are shown for each. More complex secondary flow formation and increased changes in vorticity and helicity are seen with better VO2 maxBack to article page
