Sorry that you was duped, this is really poor as you’re already aware. With a Norwood 7 pattern and such extensive loss it would have taken multiple hts/BHT and great skill to get a acceptable result. What’s happened here is poor planning, a graft count which is way too low even if it was the 1500 they claimed.
It’s possible that a lot of decent/ethical clinics would have classed you’re case as unsuitable for a transplant.
I have seen nothing but poor work/results from this particular clinic.
