Pulmonary stenosis
PV stenosis combines obstruction level with peak and mean CW Doppler velocities and gradients.

Simple approach
Pick the obstruction level first: valvular, infundibular, or supravalvular. Then enter peak velocity and the linked peak gradient. Add mean velocity and mean gradient when measured.
Detailed tutorial
The stenosis level changes the interpretation. Valvular obstruction is the common default, while infundibular or supravalvular obstruction should be selected when imaging or Doppler localization supports it.
Peak velocity and gradient describe maximal obstruction. Mean gradient adds haemodynamic context when the envelope is complete and aligned. Always consider RV function, flow state, and image quality when interpreting gradients.
