I also had genetic testing done after they found a 5.2 cm ascending AA at 54 years old (5 years ago). I also had had a brain aneurysm and there had been several confirmed cases in my family, including my brother who has 3 brain aneurysms. In my case my cardiologist who is an aortic disease specialist is also a geneticist and he was conducting research. My individual results showed that I didn’t have any of the known markers but based on the family history he thought my family could have an unknown marker. So my family’s involvement was more to help others than myself or my immediate family members. I also have a BAV and those are known to be contributors to the appearance of aneurysms, so double whammy for me. As there were no known markers in my family, my children got echocardiograms and brain MRIs , both negative but they are young so they have to repeat every 4-5 years. My siblings also got tested and besides my brother, the rest are clear. I’m also the only one with a BAV.

Genetic testing is good if you have a known marker since it may give you an indication your family (on whichever side the marker comes from) needs to be assessed for possible aneurysms.

As @moonboy says now that the aneurysm is known, you became uninsurable, at least for life insurance. I do have long term care insurance.

I had both of my aneurysms repaired, and 5 years on I’m in very good health.

My recommendation, keep yourself healthy, exercise (sensibly, listen to the restrictions given by your surgeon and cardiologist) , treat your body well. You want your body to be in the best shape possible when and if you need surgery. Find the best thoracic surgeon you can find, and a cardiologist who is an aortic disease specialist.

Wish you the best!!!
