Bicuspid aortic valve with nodular calcifications (Figure 5-6), and low trans-stenotic gradient (Figure 8). The white arrow in Figure 7 shows the pre-stenotic outflow acceleration, useful to identify the stenotic orifice, so to correctly align the continuous wave Doppler to optimize sampling of the stenotic jet (Figure 8).
