If a 심장 rip from the body, is it meant he/she already dead (even without someone crush their heart?

또는 things can get back to normal if they put the 심장 again?

aurora looks like dead women walking in the last eps, we haven't see a person survive from this 심장 ripping curse. I'm really worried for aurora, innocent soul used for selfish reason, this just like graham all over again, please give me hope she will survive in the end :'(
