Towards a more standardized bicuspid aortic valve repair: Impact of active aortic annulus remodeling on 4D flow MRI patterns and functional outcome
Additional caption:
[A] Velocity-coded 4D flow MRI reveals an accelerated eccentric asymmetric flow jet (indicated by yellow and red streamlines) and a pronounced vortical flow pattern (arrows) in the ascending aorta before surgery. The flow jet impacts and travels along the right aortic wall. [B] After surgery, velocity-coded 4D flow MRI shows reduced vortical flow with a more cohesive central flow pattern more parallel to the vessel wall of the ascending aorta.
