You might want to check out the American heart association guidelines for aortic aneurysms. I think it can be googled. They came out updated in 2022? I think they lowered the size to 5.5 for surgery for a three leaflet valve which is the normal configuration a two leaflet valve is more likely to have issues and so they, do surgery sooner I think at 5.0 I looked at and it was very helpful. Someone also on here told me about square breathing, where you breathing through your nose 4 seconds, hold it four seconds and breeze out through your mouth for four seconds… It takes you out of fighter flight and put you into rest and digest. In other words, it tricks your body into thinking your calm and your blood pressure is rising because of stress it will go back down I feel that really helpful because when I first was diagnosed that was terrified, but I am at peace now and my 4.2 cm aneurysm has remained stable for the last year and a few months
