"Ross/Kono Procedure, which is the
moving of the pulmonary valve to become the aortic valve, replacing the pulmonary with a donor valve."
So it sounds to me like your going to have a Ross Procedure done, if I'm reading correctly. If this is the case, you need only to choose a valve as a back up plan.
First things first, you gotta calm down. All of this is speeding at you, but your going to be alright. Once your calm enough, look into valve choices. Mechanical will give you the best chance at not having to have this surgery again, but if your female and plan on kids, tissue would be a better route to choose. With mechanical, you'd require lifetime Anticoagulation therapy with Coumadin. It's not a bad thing, but many of painted horrible horrible pictures about it. Most of it's from old school days when people didn't know any better, but over the last ten years, things are changing. Tissue valves don't require ACT and some of the newer valves are lasting up to 20 years, but then need replaced. The question you have to ask yourself is, do you want to go through it again later in life? Now mind you, having a mechanical valve does NOT guarantee that it won't need replacing, but it's vary rare that it needs replaced.
Your next step should be making sure it's a Ross/Kono your having and then making a back up plan incase that one falls through. Go no farther then this for the time being.
