Aortic Valve Regurgitation, or Aortic Regurgitation, is a condition that occurs when your heart's aortic valve doesn't close tightly. It happens when there is leakage of the aortic valve each time the left ventricle relaxes.

A leaking (or regurgitant) aortic valve allows blood that was pumped out of your left ventricle to leak back into it.

You can have aortic regurgitation for a long time and not know it. It may take years for symptoms to start (chronic aortic valve regurgitation). In rare cases, the valve problem starts suddenly and without warning (aortic valve regurgitation). It requires medical help right away.
