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  :

Symptoms are usually mild but include palpitations (awareness of heartbeats), a fluttering discomfort in the chest, cold skin and fatigue. Medical management usually includes drug treatment and regular doctor exams. [heart.org]
Symptoms of tricuspid regurgitation may include decreased urination, fatigue, swelling in the abdomen, feet or ankles and abnormal pulsing experienced in the neck veins. [emoryhealthcare.org]

The congenital form accounts for approximately 0.3% of all congenital heart disease cases. The frequency of tricuspid stenosis in the older population, due to secondary causes, ranges from 0.3-3.2%. [emedicine.com]
- Heart Murmur
The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. But many people have heart murmurs without having a problem. [icdlist.com]
The diagnosis of tricuspid valve stenosis usually occurs during a physical examination with the discovery of a heart murmur. Additional testing is usually performed after the discovery of a heart murmur. [rahmanicardiology.com]
A heart murmur had been diagnosed 28 years previously, and she had been followed at the Hospital for Sick Children, Toronto. She remained entirely symptom free during adolescence. .. [nejm.org]
A heart murmur produced by blood trying to flow through a stenotic valve can be heard with a stethoscope, and an x ray of the chest will show the right atrium to be enlarged. [schmidtandclark.com]
- Diastolic Murmur
A mild diastolic murmur can be heard during auscultation caused by the blood flow through the stenotic valve. It is best heard over the left sternal border with rumbling character and tricuspid opening snap with wide-splitting S1. [en.wikipedia.org]
Clinical examination classically reveals an elevated jugular venous pressure with a dominant a-wave and slow y-descent, and a mid-diastolic murmur that is heard on praecordial auscultation 1-3. [radiopaedia.org]
The differential diagnosis of tricuspid stenosis includes: Aortic regurgitation : The diastolic murmur of aortic regurgitation decreases with respiration, which is in contrast to that of tricuspid stenosis. [wikidoc.org]
Mitral valve stenosis is associated with a diastolic murmur because of turbulence that occurs as blood flows across the stenotic valve.. [cvphysiology.com]
A low rumbling diastolic murmur along the left sternal border, which increases with inspiration. Tricuspid regurgitation is often also present, causing a pansystolic murmur in a similar location. [patient.info]

Jugular venous distention may occur, increasing with inspiration (Kussmaul sign). The face may become dusky and scalp veins may dilate when the patient is recumbent (suffusion sign). Hepatic congestion and peripheral edema may occur. [merckmanuals.com]
Isolated tricuspid stenosis is manifest by the signs and symptoms of right-sided heart failure, including hepatomegaly, hepatic dysfunction, ascites, edema, and jugular venous distention with giant A waves visible on the central venous pressure recording [tele.med.ru]
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.
