AND....ask who is going to do this Cath and how many times he has done them AND, discuss before hand if he sees something will be just go ahead and stent an area without you knowing it and or discussing it before hand.
I have had three Caths with 3 different doctors. The last Cath doc by far was the best and most professional to me and my hubby who was waiting outside the cath Lab. He also was the oldest of the others and has done these things in his sleep and will not do anything he thinks does not need attention now. I have had 2 unnecessary stents.(second cath) ..
Ask a lot of questions. Don't let any doctor intimidate you.
Good Luck.
