The aortic valve is a passive valve, made up of three leaflets which assume the shape of half moons (semi-lunar). Opposite to the mitral valve, there is no true aortic fibrous annulus but a complex root made up of the aortic wall sinuses, left ventricular myocardium, and interleaflet fibrous triangles. The ostia of the coronary arteries are located within the aortic sinuses. The sino-tubular junction is an important anatomic landmark for surgical procedures. It may be that the leaflets of the aortic valve are not passive as they are rich in different types of nerve endings. The function and role of these “nerves” remain obscure.

摘要

The aortic valve is a passive valve, made up of three leaflets which assume the shape of half moons (semi-lunar). Opposite to the mitral valve, there is no true aortic fibrous annulus but a complex root made up of the aortic wall sinuses, left ventricular myocardium, and interleaflet fibrous triangles. The ostia of the coronary arteries are located within the aortic sinuses. The sino-tubular junction is an important anatomic landmark for surgical procedures. It may be that the leaflets of the aortic valve are not passive as they are rich in different types of nerve endings. The function and role of these “nerves” remain obscure.
