Anita posted to Colin's care page that he was out of surgery at 12:30 today and that everything went well. He came off of the bypass machine with no problems (that was the scariest part), WHOOO-HOO! :)
They were going to be able to see him around 2:00. Still no updates after this one, so I'm guessing that no news is good news.
Thanks everyone! I'll let you know how he's doing when I find out!
