(A,B). Representation of morphologic chacteristic of the bicuspid aortic valve influencing the pattern of aortopathy. The fusion pattern of the aortic valve cusps is responsible for changes due to shear stress on the aortic wall and in the resulting flow pattern. (A) In the right–left fusion model, the jet is directed towards the right anterior wall of the ascending aorta, where it moves in a right-hand helical direction to promote dilation predominantly of the ascending aorta. (B) In contrast, in the model characterized by a fusion of the right and non-coronary cusps, the jet is directed towards the posterior wall of the aorta, so the model of shear stress of the wall it causes can favor aortic expansion at the internal proximal arch.
