"peds CT", or congenital heart surgery as they would like to be called is a very unique sub-specialty.
I have had the privledge of rotating as a CT resident on one of the top congenital services in the world. These guys are the best of the best. It is one of the purest, refined forms of surgery in the sense that they need to understand the most complex physiologic/hemodynamic situations of these weird heart lesions, not to mention the technical skills they need to fix them.
Even the traditional "big-boys" (adult cardiac, peds surgery, neurosurg) can't hang with these guys- in fact congenital surgeons look down on them.
These guys dont put in chest tubes for parapneumonic effusion, or fix tracheaesophegeal fistulas, do lung resections or even ligate the average patent ductus arteriosus- they relegate these menial tasks to the pediatric general surgeons. Its funny how even a highly competitive field like peds general surgery can be looked at as a dumping ground by another service!
There is only one way to arrive at this pinnacle of surgery- complete dedication. hard work itself is not enough. PGY-10+ are common in this field. getting into a congenital fellowship is relatively easy. I bet there are less than 20 per year who seriously pursue this field. This is one of the few fields where you have to have superior technical skill to succeed. There are some cases I cant ever see how someone could let a resident attempt! getting a job is the hard part. everyone knows everyone.
in the old days, adult cardiac surgeons did the pediatric cases too- Most of the old timers from the golden days of the Cooley era have retired. These guys did congenital cases because they invented the techniques and they filled the void. Today, very few if any residents who come out of CT fellowship are exposed to enough "peds CT" to do anything more than simple ASD, VSD. The requirements for cardiac residents is 10 congenital cases, and general thoracic residents dont need ANY congenital cases!! its just too specialzed now.
It is an interesting field, but I could never do it...
