This is the third time you've posted the same question. And it's been answered on several threads, before. (I've, again, also tagged your post).

Here is the trivia -
Although never mentioned or confirmed, Rebekah once stated that she'd like to remove Klaus' heart and "watch it grow back," though it is unclear if this would actually happen since Elijah attempted to kill Klaus this way.
It is likely that this was just an expression, as Elijah would have been successful had he ripped out Klaus' heart while Bonnie used her empowered magic to leave Klaus on the verge of death, weakening the magic that maintains an Original's abilities and immortality. No creature on either show can survive heart extraction, thus if somehow an Original could have their heart ripped out from their body being weakened such as when Klaus almost died, then that Original would die.
