Yes, it's very obvious he messed up, but that instance alone should definitely not "destroy his career." Since I live in the Boston area, the local news which is on right after Boston Med, does these cheesy follow-ups on the serious cases from the show. This week it was the baby...he is fine. If he died from complications it would be a different story, but Dr. Myers admitted his mistake and corrected it before any damage was done.
Anyways, that article isn't very shocking to me. There isn't really a need for a pediatric heart surgery program at MGH anyways with Children's 10 mins away.
I never said it *should* destroy his career. But it was caught on film, and I don't know too many hospitals who would be happy about that so I looked into it.
