Elective surgery after CHD repair?

My 6 year old had their ASD repaired percutaneously last year and they are now scheduled for tonsillectomy/adenoidectomy in a few weeks. Their ASD closure and recovery was textbook and we received cardiac clearance for this upcoming surgery but I am scared - again. I’m not worried about the tonsillectomy recovery and I have total faith in our surgeon (she removed my other kiddo’s tonsils), I think it’s just PTSD. Even though my kid’s ASD procedure was successful it was a traumatic experience for me - from diagnosis all the way to recovery. Not that it matters, but their ASD was an incidental finding and just like so many others we were shocked when we received the news. Anyway, I’m beginning to wonder if we should even go through with surgery that is purely elective even though there will be benefits to having it done - tonsils are constantly enlarged, constant sore throats, mild sleep apnea, horrible sleeper, always irritable in the mornings, mouth breather, has trouble concentrating and breath smells bad even though oral hygiene is good.

Has anyone else gotten any elective surgeries done post CHD repair? Could be days, weeks or years in between.
