Thoughts, prayers, whatever it is you do...

My father was sent to the hospital Monday after having a not so good stress test on his heart. He was sent to our local hospital and had a heart cath done yesterday. It showed 2 problems and they decided they were going to transfer him to a larger hospital in Boston. He was transferred today and will be going in for surgery in about an hour. He has had quite a few heart surgeries in the past and this one had him very worried. We would appreciate thoughts, prayers or whatever!
