Mammalian organs have already been successfully cryopreserved, thawed, and transplanted.

As far as I can see from reading the abstract of this citation, there is no actual cooling down in liquid nitrogen involved, only perfusion with a cryoprotectant. Please give a quote, find another citation, or retract the claim (I don't follow the literature, so don't know whether the claim is true; the cited paper is from 1994, so a lot could've changed).

From Greg Fahy's wikipedia article:

In the summer of 2005, where he was a keynote speaker at the annual Society for Cryobiology meeting, he announced that Twenty-First Century Medicine had successfully cryopreserved a rabbit kidney at -130ºC by vitrification and transplanted it into a rabbit after rewarming, with subsequent long-term life support by the vitrified-rewarmed kidney as the sole kidney.

Here's an abstract of the relevant paper with a link to the PDF.

I knew it had been done but I linked to the wrong abstract in my original post.
