I know exactly what you are going through. I had my surgery on my ascending thoracic aneurysm March 6 of this year. I was very nervous as well, but kept thinking I’d rather go through the surgery then have the aneurysm dissect or rupture. I had no complications during the surgery. They did repair my bicuspid valve and also they repaired the, aortic root, along with taking care of the aneurysm replacing it with a sleeve. I was in the hospital for seven days and my recovery has been relatively easy. I continue to go to cardiac rehab through the end of June. It is definitely a relief to not have to worry about the aneurysm anymore. I’m a 70-year-old female and mine was repaired at a 4.9. Trust your surgeon, the nurses and everyone that’s involved in your aftercare. It will be over with before you know it. sending you prayers and well wishes.
