After my 4-year hiatus, returning to the wards has been an exciting yet daunting transition for me. It didn’t help, of course, that I started with pediatric cardiology at Children’s Hospital, which isn’t exactly your typical patient population. I mean, I may not know how to care for a baby with fever or diarrhea, but if the kid has tetralogy of Fallot, I’m your man. In fact, after 2 weeks on the service, I was beginning to think that hypoplastic left heart syndrome was an epidemic in Boston. Unfortunately, just when I was getting to know what I was doing, when I finally figured out why the interns laughed when they called me a Bidirectional Glenn, I was switched to another service. It’s kind of weird going into general pediatrics now. Knowing little else, I think I’ll just have to put congenital heart disease as the top differential for every patient.
