Hello....I'm in a similar situation as you, 70 y.o. with afib, BP issues and an enlarged thoracic ascending aortic aneurysm...4.5cm from a recent scan. It's important to be your own best advocate with regard to doctors and medical help. Inform/educate yourself as much as possible about your health challenges, act on the recommended guidance, and insist on regular monitoring! Things may go well, and result in no growth, or at least slow growth. Find an aortic center near you where you can get some expert support. Too often, as evidenced by other stories you read here, cardiologists are uninformed, or under educated about aneurysms, but won't admit it. Find a Dr willing to monitor you regularly that is familiar with your problem. If you have the interest, look to the "Virtual Second Opinion" offered by Cleveland Clinic, which is in the top-tier of aortic centers in this country. Best of luck in your efforts going forward!! Knowledge is power, and may save your life!!
