Flow displacement in the ascending aorta before and after aortic valve repair in patients with adult congenital heart disease. Flow displacement was significantly reduced after surgery (0.3 ± 0.1 vs. 0.25 ± 0.1) at the level of the mid-ascending aorta (midAAo). There was no significant reduction in flow displacement at the level of the sinotubular junction (STJ) and the proximal aortic arch (proxAA). Red lines indicate patients with unicuspid aortic valves and diamonds indicate patients with additional aortic root remodeling
