Figure 1 Pulsed-wave Doppler and continuous-wave Doppler. A, Initial pulsed-wave Doppler gate from apical five-chamber view sampling left ventricular outflow tract velocity could not be registered accurately because of aliasing. B, Continuous-wave Doppler gate from apical five-chamber view sampling of left ventricular outflow tract velocity revealed a maximal velocity up to 6 m/s and respiratory variation in left ventricular outflow tract in the setting of sinus tachycardia.

Figure 2 Continuous-wave Doppler after treatment of dynamic left ventricular outflow tract obstruction. Continuous-wave Doppler gate from apical five-chamber view sampling of left ventricular outflow tract velocity revealed a maximal velocity of 1.5 m/s and peak pressure gradient of 9 mm Hg, confirming the resolution of dynamic left ventricular outflow tract obstruction.
