1 If your heart isn't working efficiently, you may feel aortic regurgitation symptoms including fatigue and short of breath.  Aortic regurgitation can develop suddenly or over decades. It has a variety of causes, such as rheumatic fever or infection.
Watch an animation of mitral valve regurgitation. A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve â as it should â and some blood flows back into the atrium.f regurgitation is severe enough, the forward flow of blood is reduced enough to cause heart failure (when the heart does not pump enough blood to the body) which may produce also symptoms ranging from shortness of breath during exertion, coughing, congestion around the heart and lungs, swelling of the legs and feet.
