@shayne1970 I recommend finding a good thoracic surgeon if you are worried and think you may eventually need to have it repaired. I had an Abdominal Aortic Aneurysm that was 7.9 and a 6.0 ascending that were both repaired in 2024 (6 months apart - 2 different operations). I’m also living with a third one that is 4.5 (I sometimes forget I still have one). I rarely speak to my cardiologist. My yearly CT scan is with my Thoracic Surgeon who did the operations. I’m 53, never smoke and played sports my whole life. No genetic link either. All the best!
