Symptoms of Heart Valve Diseases
The main sign of heart valve disease is an unusual heartbeat sound called a heart murmur. Your doctor can hear a heart murmur with a stethoscope. However, many people have heart murmurs without having heart valve disease or any other heart problems. Others may have heart murmurs due to heart valve disease, but have no other signs or symptoms.

Heart valve disease often worsens over time, so signs and symptoms may occur years after a heart murmur is first heard. Many people who have heart valve disease don't have any symptoms until they're middle-aged or older. Other common signs and symptoms of heart valve disease relate to heart failure, which heart valve disease can cause. These signs and symptoms include:
-- Shortness of breath, especially when you exert yourself or when you're lying down
-- Swelling in your ankles, feet, legs, abdomen, and veins in the neck
-- Unusual fatigue (tiredness)

Other Signs and Symptoms
Heart valve disease can cause chest pain that may happen only when you exert yourself. You also may notice a fluttering, racing, or irregular heartbeat. Some types of heart valve disease, such as aortic or mitral valve stenosis, can cause dizziness or fainting.
