Pulmonary Valve Stenosis

Pulmonary Valve Stenosis (PVS) is a heart condition that affects the pulmonary valve, a tiny door-like structure between the right ventricle (lower chamber) and the pulmonary artery. This valve controls the flow of blood from the heart to the lungs, where oxygen is added to the blood. When the pulmonary valve becomes narrow or blocked, it can cause various problems. In this article, we’ll explain PVS in simple terms, covering its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgery options.

Types of Pulmonary Valve Stenosis:

  1. Valvular Pulmonary Stenosis: The most common type, where the valve itself is narrowed.
  2. Supravalvular Pulmonary Stenosis: A less common type where the narrowing occurs just above the valve.
  3. Subvalvular Pulmonary Stenosis: Another rare type where the narrowing is below the valve.

Causes of Pulmonary Valve Stenosis:

  1. Congenital Heart Defects: Many cases of PVS are present at birth due to abnormal valve development.
  2. Genetic Factors: Sometimes, it runs in families.
  3. Rheumatic Fever: An infection that can damage the heart valves.
  4. Carcinoid Syndrome: A rare condition that can affect the pulmonary valve.
  5. Endocarditis: An infection of the heart lining.
  6. Previous Heart Surgery: Scar tissue can narrow the valve.
  7. Trauma: Injuries to the chest or heart can lead to PVS.
  8. Calcium Deposits: Build-up of calcium on the valve can cause narrowing.
  9. Tumors: Rarely, tumors can grow on or near the pulmonary valve.
  10. Radiation Therapy: Previous radiation treatment can damage heart valves.
  11. Inflammatory Conditions: Conditions like lupus can affect heart valves.
  12. Kawasaki Disease: An illness that can harm the heart.
  13. Cleft Palate: Associated with some cases of PVS.
  14. Neurofibromatosis: A genetic disorder that can affect the heart.
  15. Noonan Syndrome: Another genetic condition linked to PVS.
  16. Williams Syndrome: Rare genetic disorder affecting heart development.
  17. Down Syndrome: Some individuals with Down syndrome may have PVS.
  18. Alagille Syndrome: A rare genetic disorder that may cause PVS.
  19. Trisomy 13: A chromosomal disorder associated with heart defects.
  20. Maternal Drug Use: Certain medications taken during pregnancy may increase the risk.

  13. Radionuclide Ventriculography: Measures how well the heart pumps.
  14. Transesophageal Echocardiogram (TEE): A specialized echocardiogram using a probe down the throat.
  15. Pulmonary Function Test: Evaluates lung function.
  16. Genetic Testing: To identify any underlying genetic factors.
  17. Heart Biopsy: Rarely, a small piece of heart tissue may be examined.
  18. Exercise Tolerance Test: Measures how the heart responds to exercise.
