Some cases of aortic insufficiency can be prevented by treating underlying disorders. For example, effective treatment of autoimmune disorders may prevent some damage to the aortic valve. High blood pressure can be managed with lifestyle changes and medicines. Following safer sex guidelines can prevents some STDs.
Aortic regurgitation may worsen if a person has a heart infection or aortic dissection. The function of the left heart chamber may deteriorate quickly within a few weeks or months. Chronic regurgitation usually progresses slowly. It can cause severe congestive heart failure, or CHF.
Aortic regurgitation is not contagious and poses no risk to others.
