Yeah, a lot of Marfan's patients are sudden aortic dissections. I think it gets mixed up with certain pituitary problems a lot or, as you said, diagnosed posthumously.
The track star I knew was long and lean. I'm trying to remember if he had other hallmarks of Marfan's (the long fingers, the posture checkpoints) and I think he did. But I don't know what the specific diagnosis was and it was never my place to intrude and ask. I just remember it being such a tragedy and a shock to see this poor guy, who had gotten into college on a track scholarship, in a casket before school even started
