Aortic Valve (2026)

When the left ventricle contracts, pressure rises until it exceeds the pressure in the aorta. This forces the leaflets open, allowing blood to surge into the systemic circulation.

In a healthy heart, the valve typically consists of three thin, half-moon-shaped flaps called leaflets or cusps . aortic valve

The aortic valve is one of the four main valves in the human heart, serving as the final "gatekeeper" that regulates blood flow from the left ventricle into the aorta . Its primary function is to ensure that oxygen-rich blood moves in a single direction—out to the rest of the body—while preventing any backflow into the heart.

The valve operates based on pressure differentials between the heart and the body. The aortic valve is one of the four

The aortic valve is located at the aortic root , where the left ventricle connects to the ascending aorta.
