WebAortic regurgitation. Aortic regurgitation ( AR ), also known as aortic insufficiency ( AI ), is the leaking of the aortic valve of the heart that causes blood to flow in the reverse direction during ventricular diastole, from the aorta into the left ventricle. As a consequence, the cardiac muscle is forced to work harder than normal. the road wendy lyrics
