Tricuspid Stenosis

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 [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]:

  • 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]
  • 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]
  • Nevertheless, patients who are diagnosed with the condition tend to present with the following symptoms: Fatigue Dyspnea Abdominal discomfort and ascites, due to systemic venous congestion Pulsations felt by the patient at the neck area Peripheral edema[symptoma.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]

  • 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]

  • 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 [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.

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]
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]
Right Atrial Hypertrophy
  • Investigations ECG: findings are usually nonspecific; they may show right atrial hypertrophy (tall peaked 'p' waves), incomplete right bundle-branch block, Q waves in lead V1, and atrial fibrillation.[patient.info]
  • atrial hypertrophy. [18] Patients with TS experience frequent arrhythmias, particularly atrial flutter and/or atrial fibrillation due to the enlargement of the right atrium.[wikidoc.org]


  • The treatment is usually by surgery (tricuspid valve replacement) or percutaneous balloon valvuloplasty.[en.wikipedia.org]
  • Aggressive treatment consisted of surgical extraction of two pacemaker leads and one pacemaker battery, replacement of the tricuspid valve and implantation of a DDD-R epicardial pacemaker.[ncbi.nlm.nih.gov]



  • 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]
