Athlete recovery time?

We’re new to CHD. My 15 year old son was diagnosed with PAPVR with a 2.6 left right shunt in July, but he was asymptomatic and they allowed him to continue his hockey season (goalie) without surgery under close monitoring. His OHS is now coming up on May 5th at Children’s Hospital Los Angeles, but I have no idea what to expect. How soon should we expect him to return to goaltending? What items should I have for him in the hospital and at home? How did you navigate work and caregiving during recovery? I’m a single mom with a ton of anxiety so I’d like to be as prepared as possible!
