Hi, Yes I've had about a dozen or so. I'm a heart transplant recipient and to insure at the beginning that your not rejecting you have a lot of them.
The process is done under local Anastesia and usually in the neck area to access an artery. But also the groin area and arm are options. It's not very long procedures usually about 15 minutes and typically can leave after the procedure is completed. And a short recovery period to make sure the incision is closed. If you have it by the groin it's a longer recovery of about 3-5 hours to make sure that the artery is closed and you have to lay flat for a period of time. So for length of time at the hospital the neck is the best method
Please ask any questions you like. I can explain further
