Mitral Valve Regurgitation - What Increases Your Risk

Risk factors for mitral valve regurgitation (MR) include:

  • Age. Wear and tear of the mitral valve occurs over time. This increases the likelihood of blood leaking back into the atrium.
  • Having mitral valve prolapse.
  • Having had rheumatic fever, because it can cause scarring on the valve. This can result in incomplete closure.
  • Coronary artery disease (CAD). CAD may cause ischemia (reduced blood flow) or infarction (heart attack), which affects the valve's structure. This can lead to incomplete closure.
  • Less commonly, diabetes and Marfan's syndrome, because they may lead to hardening of the valve.
