Shortly after the events of the Heart of Hush, Batman R.I.P., Final Crisis, and Battle for the Cowl storylines, Hush cuts out Catwoman's heart, Batman retrieves it, and Zatanna heals her. Catwoman gets her revenge by stealing all of Hush's money and giving it to Gotham City's female criminals, Harley Quinn and Poison Ivy, as well as Holly Robinson. Bruce Wayne is thought to be dead and is replaced by Dick Grayson. (Summary taken from Wikipedia)
