As long as your aortic root isn't too dilated, replacing the ascending aorta itself doesn't add a ton of time to your operation, assuming your head vessels aren't involved and/or aneurysmal. If your root is involved, they'll have to reattach your coronary arteries to the aortic graft and will likely do what is called a bentall procedure. Lots of possibilities. Stay positive and be glad you didn't need this operation sixty years ago. Any big heart center does these multiple times a week.
