Mitral Valve Regurgitation

Mitral Valve Regurgitation

Mitral valve regurgitation occurs when the heart’s mitral valve does not close properly. Blood will regurgitate or flow back into the heart causing an insufficient amount of blood to flow throughout the rest of the body.

Over time, certain diseases or conditions can cause the mitral valve to malfunction:

  • Damaged mitral valve tissue cords
  • Bulging mitral valve leaflets
  • Rheumatic fever (untreated strep throat)
  • Endocarditis (heart lining infection)
  • Cardiomyopathy
  • Heart attack
  • Trauma
  • Prolong drug use
  • Congenital heart defects
  • Radiation
  • Atrial fibrillation

Mitral valve regurgitation may not become symptomatic for years. Fatigue, shortness of breath, swelling, a heart murmur or rapid heartbeat are the potential warning signs of a mitral valve malfunction. If the valve defect onsets quickly and the damage is severe, this usually results in more intense symptoms.
