Which treatment works the best and fastest for aortic regurgitation?

Valve replacement: Aortic regurgitation, or a leaky aortic valve can be well tolerated, but when severe will lead to heart failure. When significant, and especially when the heart function is decompensating, aortic insufficiency is treated with aortic valve replacement or repair.

Depends on severity: Lacking other abnormal findings, for mild to moderate aortic regurgitation, medical therapy with blood pressure medications is usually sufficient. For severe, depending on symptoms, size of heart and structure of the valve as well as overall patient condition, surgery may be needed.
