As others have said, you can request for a fellow to not be present for the procedure.
I get it, but just to be clear, the idea of "see one, do one, teach one" is just a saying. If it is an interventional fellow, then that means they have already gone through 3 years of Cardiology training and are already board certified for cardiac cath. They then are spending another 1-2 yrs of time dedicated solely to stenting procedures. This allows for them to get a lot of experience quickly. By the end of my interventional fellowship I had done well over 700 interventions. Meanwhile in practice, most are probably closer to 100 (and many much less) per year.
I would also point out that it's different everywhere and pretty individual too and you have no real way of knowing what your situation will be. There are plenty of fellows that are awful. But when I was a fellow there were several attendings that were awful in the lab and essentially dependent on the fellow to do the case. If someone would have taken their fellow away, it wouldn't have been good.
Just trying to stick up for the interventional training process. But it's your body and your decision. So go with whatever makes you most comfortable. I'm sure everything will go well. Best of luck.
