a heart cath on Wednesday at 1. We have to be there at 9:30 for tests and prep. He has had hernia surgery in both groin areas and has had open heart surgery, so they don't know where they are going to try to go in since all the scar tissue can prevent them from getting in or tear arteries. They also said that the graft can tear when they are in there. He has had three heart caths in the past, but this time I'm scared.
