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.
Presentation
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 [1]. 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 [2].
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 [3] [4]:
- Fatigue
- Dyspnea
- Abdominal discomfort and ascites, due to systemic venous congestion
- Pulsations felt by the patient at the neck area
- Peripheral edema
Entire Body System
- Fatigue
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]

- 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]

Workup
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 [5]. 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 [6]. 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 [7] [8] [9].
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.
Blocks
- Left Anterior Fascicular Block
This case, as well as previous case reports, suggests that congenital tricuspid stenosis with ostium secundum atrial septal defect is associated with left anterior fascicular block. [ncbi.nlm.nih.gov]
Jugular Venous Pressure
- Prominent A-Wave
Patients often display a prominent A Wave as atrial systole against the stenotic tricuspid valve results in an exaggerated increase in right atrial pressure and thus bulging of neck veins. [pathwaymedicine.org]
A prominent A wave frequently is found in the central venous pressure trace. [tele.med.ru]

Treatment
The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty. [en.wikipedia.org]
Diuretics and aldosterone antagonists Rarely valve repair or replacement Evidence to guide treatment of tricuspid stenosis is scarce. [merckmanuals.com]
We believe that interventional treatment of prosthetic valvular stenosis in the setting of endocarditis is a reasonable therapeutic choice when open surgical repair is associated with prohibitively high mortality. [ncbi.nlm.nih.gov]
Prognosis
Prognosis Prognosis is generally good but dependent on the prognosis of the underlying disease, associated other heart abnormalities and associated arrhythmias. Tricuspid regurgitation [ 1 ] The incidence of TR is less than 1%. [patient.info]
Prognosis Mild tricuspid valve stenosis is not usually considered cause for surgery. [medical-dictionary.thefreedictionary.com]
Prognosis Mortality/Morbidity The mortality associated with tricuspid stenosis depends on the precipitating cause. The general mortality rate is approximately 5%. [emedicine.medscape.com]
Etiology
In over 90% of stenotic tricuspid valves, the etiology is rheumatic disease. In isolated tricuspid stenosis, the etiology is either carcinoid or congenital. [ncbi.nlm.nih.gov]
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]
Epidemiology
Other cardiac anomalies are usually present. [1] Epidemiology United States data Tricuspid stenosis is rare, occurring in less than 1% of the population. [emedicine.medscape.com]

Pathophysiology
Pathophysiology Tricuspid stenosis results from alterations in the structure of the tricuspid valve that precipitate inadequate excursion of the valve leaflets. [emedicine.medscape.com]
This occurs in a similar manner to rheumatic mitral stenosis (see individual article for detailed discussion of this pathophysiology). 1-3 The characteristic hemodynamic feature of tricuspid stenosis is an increased diastolic pressure gradient between [radiopaedia.org]
