DefinitionBy Mayo Clinic Staff
Aortic valve regurgitation — or aortic regurgitation — is a condition that occurs when your heart's aortic valve doesn't close tightly. Aortic valve regurgitation allows some of the blood that was just pumped out of your heart's main pumping chamber (left ventricle) to leak back into it.
The leakage may prevent your heart from efficiently pumping blood to the rest of your body. As a result, you may feel fatigued and short of breath.
Aortic valve regurgitation can develop suddenly or over decades. Once aortic valve regurgitation becomes severe, surgery is often required to repair or replace the aortic valve.
