Aortic regurgitation

Aortic regurgitation occurs when the aortic valve (linking the left ventricle to the aorta) does not close properly when the heart contracts. This means blood leaks back into the left ventricle, which then has to work harder to pump the extra blood away from the heart to the rest of the body. This can lead to the enlargement and thickening of the ventricle wall.
