@moonboy As usual, I agree with @moonboy but as always I highly recommend you find a cardiologist who specializes in aortic diseases, not all of them do and it makes a huge difference. Your aneurysm is on the smaller side and a cardiologist may see you more frequently than a surgeon. Having a very experienced cardiothoracic surgeon is excellent, but remember the surgeon will stop seeing you a bit after surgery (if you ever need one), the cardiologist will follow you up for life, help you control your BP which is the most important factor, and monitor to ensure you don't develop new ones. Aortic disease specialists devote their time researching everything related to aortic diseases, aortic valves, etc. they communicate with each other . To find one usually look at cardiologists and in their bios it will usually describe their interests and focus, look for "aortic diseases", or other similar phrases.

You know you have it and can plan and monitor, not everyone gets that chance!!!

All the best!!!
