The Role of the Trapped Sinus Vortex in Aortic Valve Closure
The aortic valve is one of the four valves controlling the fluid motion through the heart. It is positioned at the outlet of the left ventricle, which pumps blood into the aorta. This valve is shown diagrammatically in figure 1. It has three leaflets (cusps) and behind each leaflet there is a cavity, the sinus of Valsalva. The leaflets are very thin (0.1–0.3 mm), non-muscular and very flexible in the axial direction.
