Tricuspid valve stenosis is a condition involving a restriction of the orifice of the tricuspid valve, which correspondingly leads to diminished blood flow from the right atrium to the right ventricle.
Tricuspid valve stenosis is rarely a condition solely responsible for the symptoms reported by affected patients. Isolated tricuspid valve stenosis and congenital type of the disorder are very rare . Symptoms accompanying tricuspid valve stenosis are elicited by the condition in question, and also by mitral and aortic valve diseases, as these pathologies tend to be closely linked together .
For these reasons, symptomatology separately caused by tricuspid valve stenosis is difficult to be defined precisely. Nevertheless, patients who are diagnosed with the condition tend to present with the following symptoms  :
Due to symptoms caused by tricuspid valve stenosis and coexistent conditions being considerably non-specific, the complete workup for the diagnosis of tricuspid valve stenosis is extensive. It includes echocardiography, chest X-rays, computerized tomography (CT), and magnetic resonance imaging (MRI). Cardiac catheterization may also be indicated.
The imaging modality that is most effective in the diagnosis of tricuspid valve stenosis is the echocardiography. It can illustrate abnormal structural changes within the valvular orifice, such as thickening and fusion of leaflets, a diminished annulus diameter, and an increased blood velocity through the valve. It is also invaluable in detecting any other associated cardiac condition . Calcification of the tricuspid valve, diastolic doming, and signs compatible with the enlargement of the right atrium are findings that agree with the diagnosis of tricuspid valve stenosis . A continuous-wave Doppler ultrasound can measure transvalvular velocities which can be utilized to calculate the mean pressure gradient. In patients affected by serious tricuspid valve stenosis, the mean pressure gradient exceeds 5 mmHg   .
Plain radiography of the chest can help to observe a potentially enlarged heart. The enlargement of the right atrium may be particularly pronounced. CT of the heart typically illustrates fused and abnormally thick leaflets while MRI is able to confirm the existence of diastolic doming and a restriction in the process of valvular opening. Cardiac catheterization may be used to aid in the planning of the optimal surgical procedure, as it can diagnose many aspects of cardiac pathology.
