Summary
More in my Avengers AU.Tony's heart situation isn't in anyway simple and the surgery isn't such a fix-it as much as it is an impossibly bad scenario made worse.
Note
I understand why they wanted to get rid of the arc-reactor, story progress wise, and that it's not what makes Tony the hero he is anymore than the suit does-he makes them significant not the other way around. But it was hard not to have problems with it for other reasons.
