What is a thoracic aortic aneurysm?

Thoracic aortic aneurysm, or TAA, is an abnormal widening of a part of the thoracic aorta. The thoracic aorta is the large artery (blood vessel) that comes from the heart and extends down the center of your chest. It contains blood with oxygen that goes to the rest of the body.
