Tricuspid stenosis echocardiography

Echocardiography
The diagnosis and the severity can be assessed by echocardiography. 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

Differential diagnosis of a tricuspid mass causing obstruction

 * Right atrial tumour
 * Right atrial ball valve thrombus
 * Large vegetations
