When you have aortic valve regurgitation, the aortic valve doesn't close as it should. With each heartbeat, some of the blood leaks back (regurgitates) through the aortic valve into the left ventricle. The body does not get enough blood, so the heart has to work harder to make up for it.he most common causes of sudden (acute) aortic valve regurgitation include: 1  Endocarditis, which is an infection in the heart. 2  Aortic dissection, which means that the inner layer of the aorta separates from the middle layer. 3  Problems with a replacement (artificial) aortic valve. 4  Trauma to the heart valve or aorta.
