Aortic dissection describes a tear in the intimal layer of the aortic wall causing the formation of a false lumen. If the dissection pierces the adventitia blood hemorrhages into space adjacent to the aorta with dire consequences.
If the aortic valve leaks as a result of the damaged aorta it may be replaced at the same time. They will confirm the diagnosis with imaging tests like a chest x-ray and most importantly a CT scan to get a closer. Aortic dissection is the most common emergency affecting the aorta.

An aortic dissection is a rare serious condition in which the inner layer of the aorta the biggest blood vessel in the body coming directly from the heart tears.
