1. A system for co-registering electro-anatomical images, comprising:
a user display; and
a processor circuit in communication with the user display and configured to:
receive a first electro-anatomical image of an anatomy, the first electro-anatomical image generated based on electro-anatomical data obtained using two or more electrodes positioned on a catheter;
receive treatment location data indicating treatment locations with respect to the first electro-anatomical image, the treatment location data based on the electro-anatomical data obtained using the two or more electrodes positioned on the catheter;
receive a second electro-anatomical image of the anatomy after the anatomy has remodeled;
determine a non-rigid transformation that transforms the first electro-anatomical image to the second electro-anatomical image of the remodeled anatomy;
apply the non-rigid transformation to the treatment location data to map the treatment locations to the second electro-anatomical image of the remodeled anatomy; and
display the treatment locations mapped to the second electro-anatomical image on the user display.
