Bicuspid aortic valve fusion patterns (most commonly RL
or RN) are associated with unique flow patterns aorta
and unique patters of aortic dilation. Peak systolic
flow displacement, is a parameter derived from cardiac
MRI phase-contrast data, and quantifies the degree of
flow eccentricity from the vessel midline. We
investigated the direction of flow displacement as it
relates to valve fusion pattern with a goal of better
understanding the unique flow patterns created by
differing valve fusion patterns. We found that RL fusion
was highly associated with rightward flow jets, while RN
fusion was associated with leftward or midline flow
jets.
