Overview
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 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[1]. Stage C is defined as severe TS without symptoms. Stage D is defined as severe TS with symptoms.
| Stage | Definition | Valve anatomy | Valve hemodynamics | Hemodynamic consequences | Symptoms |
|---|---|---|---|---|---|
| C, D | Severe TS | Thickened, distorted, calcified leaflets |
|
Right atrial / Inferior vena cava enlargement |
