Q: My husband had a chest x-ray because they thought he may have pneumonia (thankfully he didn’t), and they found an aneurysm in the part of his aorta just as it leaves his heart. We have a bunch more tests ordered, but I was hoping you can tell us about this condition so we understand it better.A: The aorta is the major artery delivering oxygenated blood from the heart to other arteries in the body.
