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.

The Early Years. Ellen, with her twin sister Elizabeth, was born November 26, 1827, to Robert and Eunice Harmon. With eight children in the family, home was an interesting and busy place. The family lived on a small farm near the village of Gorham, Maine, in the northeastern part of the United States. However, a few years after the birth of the twins, Robert Harmon gave up farming, and, with his family, moved into the city of Portland, about twelve miles east.
