It is a tear in the wall of the aorta that causes blood to flow between the layers of the wall of the aortaand force the layers apart.
Good.
"Separating aorta" might refer to an aortic dissection. An aortic dissection is a life-threatening aortic condition in which the inner layer of the aorta is torn. This causes blood to collect in the space between the two layers. This blocks blood flow, causes the tear to enlarge and weakens the outer wall of the aorta, which can lead to this wall rupturing. Medical attention at a center specializing in aortic disease should be sought immediately for suspected aortic dissection.
A dilated aorta is an aorta that is wider than normal. This is indicative of an aortic aneurysm, or a bulging of the aorta due to a weakening in the walls of the aorta. Aortic aneurysms are dangerous because they can cause the walls of the aorta to tear--aortic dissection--or rupture completely, leading to severe internal bleeding. Aortic aneurysms are repaired with surgery, but can sometimes be monitored to avoid or delay surgery. Because of the life-threatening risks associated with aortic aneurysm, medical consultation should be sought.
An aortic aneurysm is a blowout about to happen. If it never ruptures then the person can live indefinitely, but if it does tear then you can lose your entire blood supply in under a minute. That's fatal - 100% of the time. Unless you are very lucky (have the rupture in an operating room) it is not survivable. (The pain as the tear begins is often the only warning). Aortic aneurysm is automatically fatal as this medical emergency suddenly curtails blood supply to the body. See the related link for further information.
Aortic dilation is the widening of the aorta. This widening could be an aortic aneurysm.
An expansion of the aortic vein
i have aortic torsion.What does it mean?
Aortic stenosis
It is an aortic arch with an aneurysm.
Aortic valve replacement is necessary when the aortic valve has become diseased. The aortic valve can suffer from insufficiency (inability to perform adequately) or stenosis.
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
They are responsible for holding up the aortic feet.
