Apical 5-chamber (AP5Ch—(A)) and right sternal edge (RSE—(B)) continuous wave spectral Doppler tracings from a patient with aortic stenosis. Left ventricular outflow tract (LVOT) diameter was 2.1 cm and LVOT velocity time integral (VTI) 22 cm. Peak transvalvular velocity, mean gradient and effective orifice area were 2.6 m/s, 13 mm Hg and 1.40 cm2, respectively from the AP5Ch view but 3.4 m/s, 21 mm Hg and 1.05 cm2, respectively using RSE Doppler data. Thus, discordant moderate aortic stenosis (AS) became concordant moderate AS using the non-apical continuous wave Doppler data.
