Where the Heart of Anti-Shurtugal Rises Again.

I have to ask, what would happen then? I mean, we do get to hear what happens if the Eldunarí is not disgorged, or if it breaks after the body is dead, but what happens when the Eldunarí breaks while the dragon is still conventionally alive? I think the main difference would be the dragon would have much more difficulty with using magic and of course they don't get a second life, but I can't think of anything else.
