How serious is an ascending aortic aneurysm?

An ascending aortic aneurysm is a serious health risk. It may rupture, causing internal bleeding that can be life-threatening. The larger the aneurysm, the greater the risk of rupture.

What is the most common cause of ascending aortic aneurysm?

Results. In the elderly, aneurysms of the ascending aorta are mainly caused by atherosclerosis. In younger patients, the most common cause is Marfan syndrome; less commonly, younger patients may have Loeys-Dietz syndrome, non-syndromic familial aortic aneurysms, or aortic valve malformations.

Is an enlarged ascending aorta serious?

An ascending aortic aneurysm is a weak spot in the top part of your aorta, which is the main artery in your body. The aneurysm bulges outward, and may cause your blood vessel wall to tear or break open. It’s a life-threatening condition.

At what size does an aortic aneurysm become a problem?

An aneurysm occurs when a portion of the aorta has enlarged to at least 1.5 times its normal size. Aortic aneurysms less than 4 centimeters in size have a low chance of bursting, but an aneurysm more than 5.5 centimeters in diameter has an increasing chance of rupturing in the next year.

When is surgery needed for ascending aortic aneurysm?

Can an ascending aortic aneurysm be repaired without open heart surgery?
