The aortic valve is one of the valves of the heart. It lies between the left ventricle and the aorta.
Morphology
The aortic valve has three cusps. These cusps are half moon shaped hence also called aortic semilunar valve. Each cusp has a small swelling in the center called the nodule. Dilatation of the wall of the aorta opposite these cusps is called aortic sinus. When the aortic valve is open, the normal size of the orifice is 3-4 cm².
Function & Physiology
During ventricular systole, pressure rises in the left ventricle. When the pressure in the left ventricle rises above the pressure in the aorta, the aortic valve opens, allowing blood to exit the left ventricle into the aorta. When ventricular systole ends, pressure in the left ventricle rapidly drops. When the pressure in the left ventricle decreases, the aortic pressure forces the aortic valve to close. The aortic sinuses help in closure of the valve by creating backflow eddies. The closure of the aortic valve contributes the A2 component of the second heart sound (S2). More on [ Aortic valve ]

American Heart Association - Defines aortic regurgitation and looks at the causes and what should be done.
Meta Description: [ The aortic valve is between the heart's left ventricle and the aorta, the large artery that receives blood from the heart's left ventricle and distributes it to the body. Regurgitation means the valve doesn't close properly, and blood can leak backward through it. ]
