Mitral Valve Regurgitation

Mitral Valve Regurgitation (MVR) is a heart condition where the mitral valve doesn’t close properly, causing blood to leak backward into the heart. This can lead to various symptoms and complications. Let’s delve into its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgeries in plain English.

Types of Mitral Valve Regurgitation:

  1. Primary (Organic) MVR: Caused by structural problems with the mitral valve itself.
  2. Secondary (Functional) MVR: Resulting from heart conditions that affect the valve’s function but not its structure.

Causes of Mitral Valve Regurgitation:

  1. Mitral Valve Prolapse: The valve’s flaps bulge into the heart’s left atrium.
  2. Heart Attack: Damages the heart muscles, affecting valve function.
  3. Rheumatic Fever: An inflammatory disease that can harm the mitral valve.
  4. Congenital Heart Defects: Malformations present at birth.
  5. Endocarditis: Infection of the heart’s inner lining.
  6. Cardiomyopathy: Diseases affecting heart muscle.
  7. Aging: Wear and tear on the valve over time.
  8. Trauma: Injury to the chest or heart.
  9. Hypertension: High blood pressure straining the valve.
  10. Ischemic Heart Disease: Reduced blood flow to the heart.
  11. Connective Tissue Disorders: Such as Marfan syndrome.
  12. Rheumatoid Arthritis: Can cause inflammation affecting the valve.
  13. Certain Medications: Such as those for migraines or Parkinson’s disease.
  14. Radiation Therapy: Can damage heart tissues.
  15. Amyloidosis: Build-up of abnormal proteins in organs.
  16. Syphilis: An infectious disease affecting the heart.
  17. Ankylosing Spondylitis: A type of arthritis affecting the spine.
  18. Myocarditis: Inflammation of the heart muscle.
  19. Hypertrophic Cardiomyopathy: Thickening of heart muscles.
  20. Systemic Lupus Erythematosus (SLE): An autoimmune disease affecting various organs, including the heart.

  3. Heart Murmur: Unusual heart sounds heard by a doctor.
  4. Palpitations: Sensation of rapid or irregular heartbeat.
  5. Swollen Feet or Ankles: Due to fluid retention.
  6. Cough: Especially when lying down.
  7. Dizziness or Fainting: Especially with exertion.
  8. Chest Pain: Usually during physical activity.
  9. Poor Exercise Tolerance: Inability to exercise as usual.
  10. Fluttering Sensation in Chest: Feeling of heart skipping beats.
  11. Rapid Weight Gain: Due to fluid accumulation.
  12. Nausea or Loss of Appetite: Due to reduced blood flow.
  13. Weakness: Feeling weak or lacking energy.
  14. Swollen Neck Veins: Visible swelling of veins in the neck.
  15. Difficulty Sleeping: Especially due to breathlessness.
  16. Pounding Heartbeat: Sensation of strong, forceful heartbeats.
  17. Fluid in Lungs (Pulmonary Edema): Leading to breathing difficulties.
  18. Anxiety: Feeling worried or uneasy.
  19. Reduced Urine Output: Due to fluid retention.
  20. Cyanosis: Bluish tint to lips or nails due to poor oxygenation.

Diagnostic Tests for Mitral Valve Regurgitation:

  1. Echocardiogram: Uses sound waves to create images of the heart.
  2. Electrocardiogram (ECG): Records heart’s electrical activity.
  3. Chest X-ray: Provides images of heart and lungs.
  4. Cardiac MRI: Detailed images of heart structures.
  5. Transesophageal Echocardiography (TEE): Probe passed into esophagus for clearer images.
  6. Doppler Ultrasound: Measures blood flow through the heart.
  7. Cardiac Catheterization: Involves inserting a thin tube into the heart.
  8. Stress Test: Measures heart’s response to physical activity.
  9. Blood Tests: To check for infections or other issues.
  10. Holter Monitor: Records heart’s activity over 24 hours.
  11. C-reactive Protein Test: Measures inflammation levels.
  12. Brain Natriuretic Peptide (BNP) Test: Checks heart failure levels.
  13. Coronary Angiography: Images blood vessels supplying the heart.
  14. Tilt Table Test: Evaluates causes of fainting.
  15. Exercise Stress Echocardiogram: Combines echocardiogram with exercise.
  16. CT Scan: Provides detailed images of heart and blood vessels.
  17. Pulse Oximetry: Measures oxygen levels in blood.
  18. Biomarker Tests: Check for heart damage markers in blood.
  19. Spirometry: Assesses lung function.
  20. Pressure-Volume Loop: Measures heart’s pumping efficiency.

Treatments for Mitral Valve Regurgitation:
