It's all mostly-irrelevant and off-topic semantics, but I'd somewhat disagree with Wikipedia :) In usability circles, a review conducted by usability experts following certain use cases would more commonly be called an "expert review".  

A classic "heuristic review" is purely systematic, taking the design one screen at a time, and running through a checklist of design principles (such as Nielsen's famous ten[1]) for each one, largely ignoring actual usage.  

Of course, in practice, most reviews tend to end up being a mixture of both techniques anyway -- even if you're doing a strictly-heuristic review, it's hard to completely detach yourself from an intended user's perspective unless you share literally none of their domain knowledge.
