Signs and Symptoms

Typically, the signs and symptoms of mitral valve stenosis may resemble those of other heart conditions.

Causes of Symptoms

  • Symptoms may show up or get worse when you increase your heart rate, as occurs during exercise.
  • Stress on the body -- such as may be caused by pregnancy or a respiratory or heart infection -- can also cause symptoms.


Symptoms often show up between the ages of 20 and 50, though they can occur at any age.

Symptoms may include:

  • Fatigue, particularly during exercise
  • Difficulty breathing, again especially during exercise
  • Awakening short of breath in the middle of the night
  • Chest pain, such as squeezing, pressure or tightness
  • Rapid or irregular heartbeats known as palpitations
  • Severe coughing, sometimes coughing up blood
  • Swelling of the legs, feet or ankles
  • Frequent respiratory infections
  • Dizziness, fainting


Complications of mitral valve stenosis may include heart failure, heart enlargement, atrial fibrillation, blood clots and lung congestion.
