Isabelle had her pre-op at Boston Children's today. She had blood drawn (cbc fine but thyroid is a little high - they may be able to reduce her meds). They did a chest xray which looked fine. They did an ekg and an echo. We met with a nurse practitioner, a surgical fellow, anesthesiology and her cardiologist. We found out this surgery will take longer and eh may be here longer and there are more complications than the first time. She's having LVOTO surgery.
