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.
