Such a thing was a rarity even in the Infernal Realm. Demon Lords would even trade parts of their fiefdom for a powerful heart.
Although there were countless demons in the Seven Hells, only the special ones would have their heart harvested. These kinds of demons were descended from powerful bloodlines and they could even be resurrected if they were strong enough.

A beating heart harvested from a 3rd Circle demon could force Counts to wage wars. But the one in Jake's hand was way stronger.
