From his parents:
Preston is out of surgery and Dr.Q says that it went much better than expected. His heart now functions normally and the pressures are good. There's a long way to go and the next 12-72 hours are VERY critical, but so far we have gotten more than we could have hoped.
Thank you for all of the wonderful prayers and comments! Please ask folks to continue praying and we'll keep you posted.
Chris & Julia
