Not much to it. Certainly painless. It was a local freezing for me and I could watch the camera exploring my arteries on the screen, kinda cool

go to u tube on google they have a great video of it and it explains it all and shows you how its done

they have a great video on the subject on u tube check it out

That's a great answer. I've had 7 angiograms with 6 turning into some procedure. Either stent or balloon. The wrist entry is silently different than the groin. Your recovery is different cause of the artery they use. The groin entrance you will need to stay more positioned in one spot for a longer recovery period of time. Wrist is much more comfortable. My only advice is. You should feel NO PAIN at the insertion. My last one on 2/14/17. I felt the insertion on the sheath and I said something and they administered more meds. But now I have a little issue with scar tissue there. Not trying to frighten you. But I am a person that wishes I had an outlet like this in 2010. Because I felt alone and many things are not fully explained. I used to suffer from "the white coat syndrome"... Every time the Dr entered my mind would go blank and I felt like I just sat there and nodded with whatever he said.
ALWAYS MAKE SURE SOMEONE IS THERE TO LISTEN TO WHAT THEY DID WHILE DOING THE PROCEDURE AND ANY SPECIFIC INSTRUCTIONS.
I love my sister because for 7 years she has never left my side. All my appointments and everything. Due to my bp dropping suddenly. I no longer drive. She is a blessing.

Wendy, It is nothing to worry about, they do a lot of these, They can look inside your artery's and parts of your heart with it. The last one I had was through my wrist, before then they had gone through my groin. You are awake and can actually watch the tube going through your arteries, (if you want) They make a small slit in an artery in your wrist or groin wherever they decide, and insert a tube into the artery. You have a local aneasthetic at the site of the opening and you really don't feel any pain, just sometimes you may feel the tube in there, they then slide another wire inside the tube and do whatever they are going to do with small tools they put on the wire. It may be stents, it may be a camera just to see what is there. It takes about 45 minutes from start to finish, unless they fit stents then it will be longer. Then they pull everything out and the close up with just a pressure pad on the wound and that's it. From there they decide what to do. Last one I had they decided to do nothing because the work done in 2004 when I had a Triple By Pass, was holding up well and decided that there was no need to operate again. I hope that helps you. It really is nothing to worry about. Colin.
