What is the aortic sinus?
Aortic sinus is one of three holes or expansion that occurs on the inner wall of rising aorts, also called the root of the aorta. Each sinus can also be called sinus of Valsalva, Sinus of Morgangni and Petit's sinus. The cavities serve as critical paths for two coronary arteries that allow the heart to function properly. These arteries supply blood to different parts of the heart that draw blood into the rest of the body.
The aortic cavities are located in the ascending aorta. The three cavities are located between each connecting point of the aortic valve. Opposite cavities are CUSPS aortic valve. The last aortic sinus ends at a sinotubular intersection in the aortic root, where the aorta becomes a cylinder or a tube similar to a structure.
The aortic cavities pass through many names. Each of the three cavities serves a unique purpose. Sinus of Valsalva, Sinus of Morgangni and Petit Sinus are used to describe the same thing. These cavities are named after the after a variety of scientists or anatomists whose research has brought a greater understanding of this oneSti body. Three cavities can be distinguished according to their position.
Three cavities are placed side by side. From left to right is the first aortic sinus the only one that is not associated with coronary artery. For this reason, it is often referred to as non -coronary sinus. It is located in the right rear valve ascending aorta.
Another or medium aortic sinus is attached to the right coronary artery. The right coronary artery supplies blood to the bottom of the left ventricle, the rear of the septum, as well as the right hall and the right chamber. This sinus is located in the left rear valve inside the aorta root.
Finally, the third and last aortic sinus is located on the right side of the aortic cavity line. It is connected to the left coronary artery. The left coronary artery is divided into two separate branches. These branches include peripheral artery and left front descending artery. The perimeter artery supplies blood to the left ventricle and papillary muscles. Left front descending arteryIt adds blood to the left ventricular septum.
occasionally there may be problems in the aortic sinus. One of these problems includes the possibility of rupture or aneurysm in sinus. Possible causes of this type of aneurysm include infectious endocarditis on the inner wall of the aorta, as well as syphilis of the tertiary stage.
