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.
