(8) Wall shear stress overload in the ascending aorta generated due to flow patterns through BAV even in the absence of stenosis or regurgitation initiates cellular signalling cascades resulting in increased expression of MMPs and growth factors leading to matrix disruption and vascular smooth muscle cell loss and decreased fibrillin; thus leading to aortopathy.
