Overview
Tricuspid stenosis (TS) staging sections into categories A, B, C, D. Stages C (without symptoms) and D (with symptoms). When valve and/or chordal thickening and calcification are evident, there are additional findings indicative of severe TS, for example, pressure gradient greater than or equal to 5 mm Hg, pressure half-time greater than or equal to 190 milliseconds, valve area less than or equal to 1.0 cm^2, associated moderate right atrial enlargement, and inferior vena cava dilatation.
Classification
Tricuspid stenosis (TS) is staged based on the valve anatomy and hemodynamics, and the hemodynamic consequences. No criteria for Stage A or B were included in the 2014 American Heart Association/American College of Cardiology valve guidelines. Stage C is defined as severe TS without symptoms. Stage D is defined as severe TS with symptoms.[1]
| Stage | Definition | Valve anatomy | Valve hemodynamics | Hemodynamic consequences | Symptoms |
|---|---|---|---|---|---|
| C, D | Severe TS | Thickened, distorted, calcified leaflets |
|
Right atrial / Inferior vena cava enlargement |
