We evaluated flow dynamics, aorta diameter and geometry
in relatives with a family member expressing a bicuspid
aortic valve (BAV) and compared results to normal
volunteers using contrast enhanced cardiac MRI and 4D
flow MRI. The findings demonstrate subtle but
significant differences in aortic hemodynamics in BAV
relatives compared to age-matched normal controls. Of
note, BAV relatives expressed more cubic shaped aortas,
which may explain the observed differences. In fact, the
significant higher vortex flow in the BAV relatives in
the ascending and descending, as well as the
significantly lower WSS was related to cubic aortic
shape.
