4D flow MRI demonstrates altered aortic hemodynamics in patients with right-left and right-noncoronary bicuspid aortic valve fusion patterns

Background Altered aortic hemodynamics associated with bicuspid aortic valve (BAV) have been implicated in the development of aortopathy in patients with congenitally altered valves[1]. Most studies have focused on the most common “right-left” bicuspid aortic valve (RL-BAV) fusion pattern [2]. This study assessed the effects of valve morphology on aortic 3D blood flow in cohorts with the most common RL-BAV fusion, less common right-noncoronary (RNC-BAV), and normal trileaflet valves.
