Thanks for the outpouring of support
Wow, what an awesome community! Thanks to all of you for the thoughts and prayers for my family.
Now, an update: Dad actually had to be taken into surgery a few hours ahead of schedule on Thursday, but after an almost 7 hour surgery he's doing quite well. He ended up with a total of 3 bypasses and a mitral valve replacement. At the moment he's still on the respirator in ICU but everything is going as planned. The surgeon was pleased with how the procedure went, and now we can start the recovery process.
Thanks again, and I'll keep you all up to date.
