My husband just called - they found scar tissue around the stints he had put in a few months ago and that was all! He will probably have to take some kind of medication to prevent that but he was still a little groggy and didn't have details. I will find out when I hopefully bring him home tonite! I had tooth surgery yesterday so I couldn't drive but today I feel better. A friend will take me down and drop me off at the hospital. Good news - thank you for the prayers!
