Anatomy Of The Aortic Valve

The aortic valves main function is to act as a gateway for blood to exit out of the ventricle during systole and push through the aorta for the body to receive oxygenated blood. It is one of the two semilunar valves of the heart the other being the pulmonary valve.

Anatomical terminology edit on wikidata the aortic valve is a valve in the human heart between the left ventricle and the aorta.

Anatomy of the aortic valve. 1 lamina fibrosa 2 lamina spongiosa and 3 lamina radialis. With each of the heart muscles contractions oxygenated blood exits the left ventricle through the aortic valve. The aortic valve cusps have 3 readily identifiable layers.

The aorta begins at the top of the left ventricle the hearts muscular pumping chamber. It functions as a one way valve. Three leaflets on the aortic valve open and close with each heartbeat to allow one way flow of blood.

Ventricular systole is a very short amount of time during the cardiac cycle for the leaflets to open and close allowing blood to exit out of the heart. The lamina fibrosa is the widest layer and faces the aortic or arterial side of the valve cusp. When the left ventricle contracts the valve only allows blood to flow out of the left ventricle and into the aorta.

The heart pumps blood from the left ventricle into the aorta through the aortic valve. The pulmonary vein delivers oxygenated blood to the hearts left atrium. Posteromedial trigone right carpentiers reconstructive valve surgery ch 5 2010.

The aortic valve is a part of the aortic root complex which is composed of the sinuses of valsalva the fibrous interleaflet triangles and the valvular leaflets themselves. The aortic valve is located between the aorta and the hearts left ventricle.

The aortic valve is composed of 4 key parts. Surgical anatomy aortic root is anchored between the pulmonary root anteriorly and mitral and tricuspid posteriorly fibrous skeleton of the heart pulmonary. The aortic valve has three cusps.

The relative positions of the aortic mitral pulmonary and tricuspid valves are shown in the diagram of the heart at the center of the figure. Then it passes through the mitral valve and into the left ventricle. The aorta is the largest artery in the body.

To appreciate the anatomy of the aortic valve it is necessary to examine its component parts and how they relate to each other so as to function as a unit. The valve comprises of the semilunar leaflets with attachments or hingelines to ventricular and aortic walls and the anterior mitral leaflet interleaflet triangles aortic sinuses of valsalva and the sinutubular junction. Approximately two thirds of the circumference of the lower part of the aortic root is connected to the septum and the remaining third is connected via a fibrous continuity known as the aortic mitral curtain to the mitral valve.
