Symptoms

Some people with mitral valve disease might not experience symptoms for many years. Signs and symptoms of mitral valve regurgitation, which depend on its severity and how quickly the condition develops, can include:

• Abnormal heart sound (heart murmur) heard through a stethoscope
• Shortness of breath (dyspnea), especially when you have been very active or when you lie down
• Fatigue
• Heart palpitations — sensations of a rapid, fluttering heartbeat
• Swollen feet or ankles

Mitral valve regurgitation is often mild and progresses slowly. You may have no symptoms for many years and be unaware that you have this condition, and it might not progress.

Your doctor might first suspect you have mitral valve regurgitation upon detecting a heart murmur. Sometimes, however, the problem develops quickly, and you may experience a sudden onset of severe signs and symptoms.

When to see a doctor

If your doctor hears a heart murmur when listening to your heart with a stethoscope, he or she may recommend that you visit a cardiologist and get an echocardiogram. If you develop symptoms that suggest mitral valve regurgitation or another problem with your heart, see your doctor right away. Sometimes the first indications are actually those of mitral valve regurgitation's complications, including heart failure, a condition in which your heart can't pump enough blood to meet your body's needs.
