Sorry, I meant to say Hi Kanaaz, (wireless keyboard) Thank you for the reference. I did read the article and there is quite a lot of medical terms I don’t understand but it does appear that the procedure has undergone many advancements in the last two years. What I learned most from it was to find the right PCI Operator who has performed more than 300 or does 50+ per year. I printed the article so I can reread it a few times and hopefully digest it further. Thanks again for your help!
