One of our chronic kids went over to the cardiac hospital because she was getting into more trouble and we thought her VSD was coming into play, but we shipped her on nitric as her PPHN was over the top! The stopped the nitric, cathed her, the VSD isn't playing any part and it is all PPHN. They started her on Viagra...we don't use it at our place and was wondering what the outcomes are with it. I hope this all goes well....she is going to be one year old in a week and had gone home and did pretty well, got pneumonia and then was up in PICU for a while. I feels so bad for her and her family
