Take your laptop to the hospital and hang out on the forum afterwards..... As MT said, it's a routine procedure these days. No worries. Will be sending some good vibes your way.......
Good Luck! I had quad bypass, & a neck vein reamed at the same time 15yrs ago. These procedures are quite commonplace nowadays, you should be fine! Prayers on the way!
My wife had her valve replaced with a (pig0 valve ) and all was great. No problems and is now on less drugs and feels great. Good Luck it will be fine.
