The aortic valve is one of the two semilunar valves of the heart, the other being the pulmonary valve. The heart has four valves and the other two are the mitral and the tricuspid valves. The aortic valve normally has three cusps or leaflets, although in 1-2% of the population it is found to congenitally have two leaflets.〔http://www.americanheart.org/presenter.jhtml?identifier=11068〕 It lies between the left ventricle and the aorta. ==Structure== The aortic valve normally has three cusps – a left, right and posterior cusp.〔 - "Heart: The Aortic Valve and Aortic Sinuses"〕
