Bicuspid aortic valve (BAV) patients with history of aortic coarctation are considered higher risk for aortic complications. We evaluated 4D flow aortic metrics in 15 BAV adults with coarctation repair (mean age 35y) retrospectively reviewed at baseline and follow-up (3.98y [2.10 to 4.96y ]). Areas of higher wall shear stress were mainly located in the arch, and 4D flow metrics remained stable at follow-up. Aortic growth was slow, with a significant increase in the anterior arch (0.25mm/y) and diaphragmatic aorta (0.27mm/y). At baseline, peak velocity at the coarctation repair site was inversely correlated to mid arch and diaphragmatic aortic growth.
