My husband’s aneurysm was 4.3 in 2007 - he was 61 yrs old.
In January 2021, his long time Mayo cardiologist retired and the new one ordered an echo. They saw a 4.8 aneurysm on the echo and CT angiogram.
It has remained stable/unchanged - last CT angio was May 2024.
My husband had never been afraid of hard physical work - lifting ungodly heavy stuff around tbe house, boat, etc.. He doesn’t do that anymore!
His first cousin (same age, healthy) also had an undiagnosed ascending aortic aneurysm which dissected. His cousin now has a descending aortic aneurysm and an abdominal one too. The cousin’s father died of something that ruptured in his chest!?!? My husband’s mother had giant cell arteritis, which is related.
Hope this is helpful!
