Morphotype-specific aortic valvular outflow jets and the degree of outflow jet eccentricity. (a) The position of the three cross-sections: at the level of the supra-valve (S0), pulmonary bifurcation (S1), and distal edge of brachiocephalic artery (S2). (b) Left, streamlines of aortic valvular outflow jet at peak systole on a ventral view. Right, cross-sections of the ascending aorta (S0–2) demonstrating flow displacement of the aortic valvular outflow jets from the vessel center. Tricuspid aortic valve (TAV) revealed no eccentric flow at peak systole. The three asymmetric bicuspid aortic valves (ABAVs) revealed markedly eccentric peak systolic aortic valvular outflow jets with high-velocity vectors occupying one-third or less of the vessel lumen. The two symmetric BAVs demonstrated mildly eccentric peak systolic aortic valvular outflow jets with high-velocity vectors occupying between 1/3 and 2/3 of the lumen.
