Pulmonary Valvular Stenosis

Pulmonary Valve Stenosis (PVS) is a heart condition that affects the pulmonary valve, restricting blood flow from the right ventricle to the pulmonary artery. This article provides an accessible overview of PVS, breaking down its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.

Types of Pulmonary Valve Stenosis:

  • Valvular Pulmonary Stenosis: Narrowing of the pulmonary valve.

  • Subvalvular Pulmonary Stenosis: Narrowing below the pulmonary valve.

Causes of Pulmonary Valve Stenosis:

  • Congenital Heart Defects: Present at birth.
  • Rheumatic Fever: Can damage heart valves.
  • Infections during Pregnancy: Can affect fetal heart development.
  • Genetic Factors: Family history may increase risk.

  • Poor Weight Gain in Infants: Difficulty thriving.
  • Swelling in Legs or Abdomen: Due to fluid retention.
  • Difficulty Feeding in Infants: Struggling to eat.
  • Clubbing of Fingers or Toes: Enlargement of fingertips.
  • Arrhythmias: Irregular heartbeats.
  • Palpitations: Feeling of rapid, strong, or irregular heartbeats.
  • Respiratory Infections: Increased susceptibility.
  • Exercise Intolerance: Difficulty participating in physical activities.
  • Pulmonary Regurgitation: Backflow of blood into the right ventricle.
  • Enlarged Right Ventricle: Visible on imaging tests.
  • Chest Tightness: Sensation of pressure in the chest.
  • Migraines: Headaches linked to heart issues.

Diagnostic Tests for Pulmonary Valve Stenosis:

  • Echocardiogram: Uses sound waves to create images of the heart.
  • Electrocardiogram (ECG or EKG): Records the heart’s electrical activity.
  • Chest X-ray: Provides an image of the heart and lungs.
  • Cardiac MRI: Detailed images of the heart’s structure and function.
  • Cardiac Catheterization: Involves a catheter to evaluate heart function.
  • Pulse Oximetry: Measures oxygen levels in the blood.
  • Holter Monitor: Records heart activity over 24-48 hours.
  • CT Scan: Detailed cross-sectional images of the heart and vessels.
  • Exercise Stress Test: Evaluates heart performance during exercise.
  • Blood Tests: Assess heart function and rule out other conditions.
  • Genetic Testing: Identifies potential genetic causes.
  • Cardiopulmonary Exercise Test: Measures cardiovascular and respiratory function during exercise.
  • Transesophageal Echocardiogram (TEE): Provides detailed images from inside the esophagus.
  • Nuclear Stress Test: Images blood flow to the heart during rest and exercise.
  • Doppler Ultrasound: Measures blood flow in the heart and vessels.
  • Chest CT Angiography: Visualizes blood vessels in the chest.
  • Ambulatory Blood Pressure Monitoring: Records blood pressure over 24 hours.
  • Fetal Echocardiogram: Evaluates fetal heart structure during pregnancy.
  • Tilt Table Test: Assesses response to changes in body position.
  • Myocardial Perfusion Imaging: Assesses blood flow to the heart muscle.

Treatments for Pulmonary Valve Stenosis:

  • Observation: Mild cases may not require immediate intervention.
  • Medication: Diuretics for fluid retention, beta-blockers for arrhythmias.
  • Balloon Valvuloplasty: Catheter-based procedure to widen the valve.
  • Valve Replacement: Surgical option for severe cases.
  • Valvulotomy: Surgical incision to open the valve.
  • Ross Procedure: Valve replacement using the patient’s pulmonary valve.
  • Transcatheter Pulmonary Valve Replacement (TPVR): Minimally invasive valve replacement.
  • Pulmonary Artery Angioplasty: Balloon dilation of the pulmonary artery.
  • Pulmonary Artery Stenting: Placement of a stent to keep the artery open.
