The Demon Heart is an Expert Mode-only item that is obtained from the Treasure Bag dropped by the Wall of Flesh. Upon use, it will give a player six total accessory slots, up from the usual five. It cannot be reused, and will not drop again for a player with either a Demon Heart in their inventory, or who already have a total of six accessory slots.
The effect is only active during expert mode. In non-expert worlds, the items in the slots are inactive and items cannot be added to the slots. Any items in them however, can be removed.
