I was diagnosed very recently that my aorta was enlaged

Were both measurements done by the same method? Depending how they do it they can get different results, when surgery is recommended depends on a lot of factors, usually when it gets to >5.0, but it depends on your body size, family history, growth rate and other factors, that is why it is important to have a cardiologist that specializes in aortic issues, at 4.5 you should also consult with a thoracic surgeon, someone in a major medical center who has done the operation many, many times. Unfortunately for ascending aneurysms, it would be open heart but don’t get ahead of yourself, consult with the specialists, they will give you all the details and follow their advice.

All the best to you and feel free to continue asking questions, a lot of people in this forum have gone through what you are going through

I want to clarify l had an echocardiogram in July 2024. At that time my aorta was 4 cm.
According to the doctor the normal ranges were (2.2 - 3.8). I was told not worry unless it enlarged. Well February 2025 went to the ER because of COVID issues. A battery of tests were done. A CT scan said borderline dialation of mascending aorta 4.5 cm. But the ER doctor never mentioned anything about it. I was told all my tests were good. I posted yesterday but if the tests results are accurate my aorta had enlarged.5 cm to 4.5cm in just 7 months. Can someone please tell me if I'm in immediate danger. I'm so stressed out. Please let me know

I have read that endoscopic repair of ascending aneurysms is being tested in clinical trials and has been successful. I pray that if my aneurysm grows to a critical size this form of repair will be being done. They are trying to make it less invasive .

Keep in mind that the measurements of the dilation are not the same every time if taken by a different radiologist of doctor. My Thoracic specialist at a University Hospital in Houston reviews my annual scan himself and does his own measurements that tend to be a bit different than the radiologists. He shows that I am around 4.5 cm but the radiologists show 4.2 cm.

As has been said, different methods Echo vs CT and different People taking the measurements would yield different results, you need to find a specialist who does the same measurement periodically to properly assess the growth rate and a baseline size. Again a cardiologist who is an aortic disease expert would be your best bet.

Thanks for your input. I just concerned of the uncertainty. I'm hoping l can at least get some piece of mind. What's your doctor's opinion of what he feels is to high of a number before it's a serious situation. The Internet can scare you to death. I appreciate getting information from someone who is going through it.
