Well, you replaced the regular with the briarheart to begin with, no one was ever born a briarheart, so in theory, yes. However, you'd be severing several aetherial connections to do so, so side effects could be disatrous at worst.
I don't think that really matters, I mean, it couldn't be any worse than the damage done by putting the briar heart in the body in the first place.
if you puted the hart then what if they are bleed then die caus they are bleed out

The heart was removed at once and replaced, they probably use some spell.
