Chronic aortic valve regurgitation is caused by a bicuspid aortic valve, rheumatic fever, enlargement of the aorta and aging. Acute, or sudden onset, aortic valve regurgitation is caused by endocarditis, trauma to the valve and difficulties with an aortic valve replacement, according to WebMD. Aortic dissection, which occurs when the middle and inner layers of the aorta separate from each other, is another cause of acute aortic valve regurgitation.

Chronic aortic valve regurgitation may not present with any symptoms in the beginning, but after time, there are several symptoms that occur. Fatigue, shortness of breath, uneven heartbeat, a racing heart and chest pain are all symptoms of chronic aortic valve regurgitation, explains WebMD. With the acute form of the disease, the same symptoms are noted but occur quickly and are life-threatening.

Acute aortic valve regurgitation requires valve replacement surgery immediately. When the condition is caught early and is properly monitored, treatment begins with lifestyle changes, notes WebMD. To keep the aortic valve regurgitation from becoming severe, stop smoking, follow a healthy diet, exercise and lose excess weight. When symptoms occur, or when the heart does not pump as efficiently, valve replacement surgery is recommended.
