Aortic valve regurgitation (also known as aortic regurgitation) occurs when a backflow of blood that was just pumped out of the heart's main pumping chamber (left ventricle) has leaked back (regurgitation) through the aortic valve. This is due to the aortic valve not closing tightly.

This blood leakage may result in the heart being inefficient in pumping blood to the rest of your body. Patients with aortic valve regurgitation often experience fatigue and shortness of breath.

This condition can develop suddenly or gradually develop over many years. However, when aortic valve regurgitation becomes severe, surgery required to repair or replace the aortic valve.
