Six months is pretty standard... This is so that the artery walls can grow over the stent and you'll get a smooth wall, thus ensuring (hopefully) no restenosis! At least that's what my cardiologist tells me - and he's a GCAA cardio to boot!
So that's UAE - and I know that JAA/UK CAA are the same. The FAA may not even go for it!!!!!
I'm currently waiting my six months for requalifying for my medical. Just one of those things
Good luck anyway
