Overview
Cardiac catheterization may be helpful in the diagnosis of tricuspid stenosis. Findings on a cardiac catheterization suggestive of tricuspid stenosis include atrial “a” wave and mean gradient across the tricuspid valve.
Other Imaging Findings
- Cardiac catheterization may be helpful in the diagnosis of tricuspid stenosis. Findings on an cardiac catheterization suggestive of tricuspid stenosis include:[1][2]
- Large right atrial “a” wave of 12 to 20 mm Hg.[3][4]
- A diastolic, mean gradient of 4 to 8 mm Hg across the tricuspid valve on right heart catheterization.
- An elevated right atrial pressure with a gradual fall in early diastole and a diastolic pressure gradient across the tricuspid valve is characteristic of tricuspid stenosis.
- On cardiac catheterization a diastolic pressure gradients between 2 to 4 may indicate significant severe tricuspid stenosis.
- On cardiac catheterization a tricuspid valve area less than 1.0 cm may also indicates severe tricuspid stenosis.

In patients with TR, invasive measurement of the cardiac index, right-sided diastolic pressures, pulmonary artery pressures, and pulmonary vascular resistance, as well as right ventriculography, can be useful when clinical and noninvasive data are discordant or inadequate.(Level of Evidence: C-LD) |
