My husband's ascending aneurysm is 4.9 with absolutely no symptoms and was discovered in a checkup. After the discovery and a CT scan, he did see, with me along with him, a thoracic cardiovascular surgeon. Since my husband has been so physically active (Peloton super high speed, weights, outdoor hiking) and was told that to be safe his is now restricted on how much he may do, we have together decided that he will be much better if he goes ahead and does the removal. That's not to say that I'm not scared--this kind of serious surgery sets off alarm bells; so I am quite anxious. Surgery happens in five days from this writing.
