Altered 4-D magnetic resonance imaging flow characteristics in complex congenital aortic arch repair

Interrupted aortic arch (IAA) is a rare but severe congenital abnormality often associated with bicuspid aortic valve (BAV). Complex re-interventions are often needed despite surgical advances, but the impact of aortic hemodynamics in repaired patients is unknown. Investigate effect of IAA repairs on aortic hemodynamics, wall shear stress and flow derangements via 4-D flow MRI. We retrospectively analyzed age- and gender-matched cohorts (IAA...
