Most often, aortic valve regurgitation develops gradually. You may have no signs or symptoms for years. You may be unaware that you have the condition. However, sometimes aortic valve regurgitation occurs suddenly, usually as a result of an infection of the valve. As aortic valve regurgitation worsens, signs and symptoms may include: 
Shortness of breath with exercise or when you lie down
Fatigue and weakness, especially when you increase your activity level
Heart murmur
Irregular pulse (arrhythmia)
Lightheadedness or fainting
Chest pain (angina), discomfort or tightness, often increasing during exercise
Sensations of a rapid, fluttering heartbeat (palpitations)
Swollen ankles and feet
