Will be praying for a good outcome. As Buzz said, bypass is fairly routine. My Father had a triple in his early 80's and lived to 98 so hopefully you'll both see many more seasons together.
Thank you everybody for all of the prayers and well wishes. They just finished up his surgery and are moving him to the ICU. He had a couple other issues that made this a bit more complicated than a normal bypass, but we knew that going in. Once again, thank you all so much. Now I get to head out there on Saturday and spend a week with him. Might have to try to shoot some coyotes while I'm there Thanks again
