Jess, my doctor very nearly sent me to Duke for a second eval in fall of '09, so I did a lot of research on them. They have incredibly fast transplant times (like 3 weeks), but the reason for this is they only actively list 3 or so people at a time. It's a funny system that allows the transplant team to pick who is going to get lungs instead of just the UNOS score. It also means they have short waiting times, b/c you will be the only one "listed" with your height and blood type. But, the flip side is that they have people who are transplant-ready but not actively listed, just waiting their turn to be one of the lucky 3.
I heard NOTHING but good things about them from people I talked to who have had their transplants there. The team seems to be really well liked by their patients. I didn't end up being evaluated there b/c I moved way up on Columbia's list, but it's a good choice center for people who need transplants soon and think they are likely to be one of the chosen few.
