Teenager with VSD, maybe ASD as well, don't remember all the details.
Severe pulmonary hypertension, awaiting heart and lung transplant, but not sick enough yet.

Eisenmenger physiology. Pulmonary pressures equal systemic at start of case with nitric, etc.

Severe scoliosis causing pulmonary complications.

1st half of case- no problem.
😴 Actually doing much better than expected. Than ...
Uh oh ...
Over 2 min pulmonary pressures go to about 2x systemic.
😱
Much drama ensues.
Pt survived, neuro intact, and left the PICU after a couple weeks.
High fives all around.

Liver transplants can be pretty dramatic from time to time. I don't miss them.
