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. Then it passes through the mitral valve and into the left ventricle.

The aortic valve has three cusps.

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. It functions as a one way valve.

The aortic valve is located between the aorta and the hearts left ventricle. Three leaflets on the aortic valve open and close with each heartbeat to allow one way flow of blood. The lamina fibrosa is the widest layer and faces the aortic or arterial side of the valve cusp.

The heart pumps blood from the left ventricle into the aorta through the aortic valve. Anatomical terminology edit on wikidata the aortic valve is a valve in the human heart between the left ventricle and the aorta. The aorta is the largest artery in the body.

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 cusps have 3 readily identifiable layers. The aortic valve is composed of 4 key parts.

When the left ventricle contracts the valve only allows blood to flow out of the left ventricle and into the aorta. Posteromedial trigone right carpentiers reconstructive valve surgery ch 5 2010. Anatomy of the aortic valve.

The pulmonary vein delivers oxygenated blood to the hearts left atrium. 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. The aorta begins at the top of the left ventricle the hearts muscular pumping chamber.

When the heart relaxes between contractions the aortic valve closes preventing blood in the aorta from returning to the left ventricle. 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. With each of the heart muscles contractions oxygenated blood exits the left ventricle through the aortic valve.

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. It is one of the two semilunar valves of the heart the other being the pulmonary valve.
