Symptoms of Mitral Valve Disease

Both mitral valve stenosis and mitral valve regurgitation affect the ability of your heart to function properly. Because these conditions typically do not occur suddenly, you may not notice any symptoms for a while.
 

Symptoms of Mitral Valve Stenosis

Mitral valve stenosis develops over time. Many patients with mitral valve stenosis may not experience any signs or symptoms until the valve opening becomes very narrow. The symptoms of mitral valve stenosis include:
  • Shortness of breath, especially when active or lying down
  • Fatigue, especially when you are active
  • Swollen feet or legs (edema)
  • Chest pain (angina), pressure or tightness
  • Feeling faint (syncope)
  • Coughing up blood
  • Rapid or fluttering heartbeat (palpitations)
  • An unusual sound between heart beats that may be due to a defect in the heart’s wall or a damaged valve (heart murmur)
  • Severe headache, trouble speaking or other signs of stroke
  • Low blood pressure

Symptoms of Mitral Valve Regurgitation

As mitral valve regurgitation develops, the heart tries to compensate. For a while — even for many years — patients may not experience any symptoms. Over time and as the condition worsens, patients may experience:
  • Fatigue and weakness, especially when active
  • Shortness of breath (dyspnea) when active or lying down
  • Swollen ankles and feet (edema)
  • Feeling faint (syncope) 
  • Rapid or fluttering heartbeat (palpitations)
  • Low blood pressure
  • An unusual sound between heart beats that may be due to a defect in the heart’s wall or a damaged valve (heart murmur)
