Aortic valve regurgitation

Overview

Aortic valve regurgitation — or aortic regurgitation — is a condition that occurs when your heart's aortic valve doesn't close tightly. As a result, some of the blood pumped out of your heart's main pumping chamber (left ventricle) leaks backward.

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.
