Severe Tricuspid Stenosis

Obstructed right atrial emptying produces elevated RA pressure relative to RV diastolic pressure.

Overview

Select Severe Tricuspid 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.

Obstructed right atrial emptying produces elevated RA pressure relative to RV diastolic pressure.

RA shows a prominent a wave and a slow y descent in sinus rhythm.

RA pressure exceeds RV diastolic pressure; the difference in displayed summary values is not a measured mean valve gradient.

Isolated tricuspid stenosis can leave PA and wedge pressures near normal.

Step by step

  1. Reset interventions if you want the untreated example.
  2. Select the condition and inspect the pressure summary and relevant waveforms.
  3. Pause for annotations; add one intervention or loading change to compare the response.
