Echocardiography
The diagnosis and the severity can be assessed by echocardiography [1]. This is the most popular tool by which to diagnose valvular disorders, as test results can help identify the tricuspid valve structure and intracardiac pathology. This knowledge may contribute information regarding the pathophysiology of the process
2D-Echocardiography
- Thickening of valve leaflets
- Calcification
- restricted mobility
- " Doming " of the leaflets
Doppler Echocardiography
- Severity can be assessed by the transvalvular gradient
- Using continuous wave doppler across the tricuspid valve in apical-4-chamber view. The peak gradient can be calculated using the modified Bernoulli equation.
- Pressure half time can be used but is not validated for triscuspid stenosis.
- calculation of Tricuspid valve area with the continuity equation
- Tricuspid valve area = ( annulus PW Vti * Cross sectional area of the annulus) / valve CW Vti
Assessment of tricuspid stenosis severity with echocardiography
| Severity | mild | moderate | severe |
|---|---|---|---|
| Tricuspid valve area | - | - | <1 |
| Mean Pressure Gradient | <4 | 4-7 | >7 |
Differential diagnosis of a tricuspid mass causing obstruction
- Right atrial tumour
- Right atrial ball valve thrombus
- Large vegetations
2014 AHA/ACC Guideline for the Management of Patients With Valvular Heart Disease: Executive Summary[2]
| Class I |
| "1. TTE is indicated in patients with TS to assess the anatomy of the valve complex, evaluate severity of stenosis, and characterize any associated regurgitation and/or left-sided valve disease. (Level of Evidence: C)" |
| Class IIb |
| "1. Invasive hemodynamic assessment of severity of TS may be considered in symptomatic patients when clinical and noninvasive data are discordant. (Level of Evidence: C)" |
