Symptoms

Some people with mitral valve disease might not experience symptoms for many years. Signs and symptoms of mitral valve disease may include:

• Abnormal heart sound (heart murmur) heard through a stethoscope
• Fatigue
• Shortness of breath, particularly when you have been very active or when you lie down
• Irregular heartbeat

When to see a doctor

If you have a heart murmur, your doctor may recommend that you visit a cardiologist. If you develop any symptoms that may suggest mitral valve disease, see your doctor.
