Jack went on a little field trip today to the cath lab. He spent about three hours downstairs while he was being checked out. Yesterday, an echo of his heart showed some pulmonary stenosis. This basically means that his pulmonary artery had narrowed for reasons that are not entirely clear. They were thinking that this could be part of the reason he continues to retain fluid. After inserting dye into his heart his function looked good and they determined that it wasn't really an issue. It was good for them to be able to look at things a little closer now that he is stable enough to withstand it. We are glad that things looked good during the cath procedure, however, it would be nice to understand a little more clearly why his body is behaving this way. Jack will be able to progress as long as his output can be 150 cc's or so more than what goes into him. So far tonight he is about half way there so we are encouraged. This is largely dependent upon his ability to avoid receiving fluids in order to improve his blood pressure. All things considered today has been a good day. He has done a good job peeing and endured his tour of the hospital without much distress. He is a brave little soldier who is doing his very best.
