There are multiple definitions:

1. maximum velocity or maximum rate of change or transition(English)

   • Abbreviation may be used in Am. Soc. Physiol. journals without definition.
   • Physiology

2. aortic valve peak velocity(English)

   • measured from the pulsed wave Doppler of the left ventricular outflow tract
   • LVOT
   • Cardiology, Diagnostics, Doppler technique

3. peak aortic jet velocity(English)

   • a direct measurement of the highest antegrade systolic velocity signal across the aortic valve. The pressure gradient can be calculated using the simplified Bernoulli equation. The risk of progression to severe aortic stenosis increased with the baseline Vmax primarily at ≥2 m/s
