Types of heart disease — mitral valve disease

Mitral valve disease (also called myxomatous mitral valve disease, endocardiosis, or atrioventricular valvular insufficiency) is a condition in which:

  • Valves of the heart do not seal properly, allowing blood to leak backward into the left atrium
  • Eventually this leads to an audible heart murmur
  • The heart loses its pumping ability and circulation is impaired
  • The heart can become enlarged from the excess blood

Mitral valve disease is a degenerative condition that progresses slowly.
