Overview
Select Severe Pulmonic Stenosis under Clinical controls → Valves. The bold italic live label confirms the active selection. These are the preset’s teaching features; combined disease, rate and interventions can change the resulting numbers.
RV systolic pressure is much higher than PA systolic pressure across the obstructed pulmonic valve.
The preset RV–PA peak-to-peak systolic difference is 55 mmHg.
The RV upstroke reaches a high systolic pressure while PA pressure stays near normal.
The gradient varies with flow in the teaching model; it is not a Doppler instantaneous gradient.
