Thanks for the prayers and warm thoughts ya'll. Grandmom's surgery went very well, the replacement valve went in just right, they were able to pull an artery from somewhere in her chest rather than her leg for her bypass, and she came off the vent this afternoon late and was able to sit up in a chair a bit!
She's a tough cookie!! She's in a cardiac ICU unit but has her own room and is being monitored closely. I was there most of today. Depending on her room, I may be spending the night with her Wednesday night. There were about a dozen of us there today but we'll be coming in shifts the rest of the week.
