What causes ascending aortic aneurysms?

ATAAs develop when a blood vessel wall becomes weak or damaged. Aging and heart disease can make the aorta less elastic. The force of blood against the weak area causes the blood vessel to bulge outward.

The following conditions can lead to aneurysms:

• Aortitis, or inflammation of the aorta.
• Atherosclerosis (plaque buildup inside your arteries).
• Bicuspid aortic valve disease (two aortic valve flaps instead of the normal three).
• Loeys–Dietz syndrome, a genetic disorder that can cause an enlarged aorta.
• Marfan syndrome, a connective tissue disorder that can affect blood vessel walls.
• Traumatic injuries can cause tears in the artery wall.
• Turner syndrome, a genetic disorder that can cause cardiovascular problems.
