Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta.

[2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
Increase in the size of the aneurysm, causing it to press on other organs, which may cause pain. Aneurysm may also rupture. It is fragile and may burst under stress. The rupture of an aortic aneurysm is a catastrophic, life-threatening event.

Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body. The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling.
