WebJohn D. Bonagura, Virginia Luis Fuentes, in Small Animal Diagnostic Ultrasound (Third Edition), 2015 Semilunar Valves. Normal blood flow in the ventricular outflow tracts is characterized by PWD velocity spectra with a roughly-triangular profile and a relatively high-pitched, whistling sound in the audio channels of the system. 140 Velocities are highly … WebThe maximum velocity, Vmax, for the LVOT should be entered above. Step 3 (Optional): If you cannot obtain a good PWD profile of the LVOT the CWD profile of the Aortic Valve frequently will exhibit a ghost profile which is contained in the CWD profile. This ghost profile can be traced as if it was a PWD profile and entered as the Vmax of the LVOT.
