Abstract

Systems and methods are provided for imaging cardiac tissue using fluorescent dyes delivered into tissue. A distal end of an imaging device may be introduced into a chamber of the heart, and fluorescent dye may be delivered into one or more body lumens in the heart such that the dye is absorbed by cardiac tissue adjacent the chamber. Images of the cardiac tissue adjacent the chamber may be acquired using the imaging device, the dye enhancing identifying cardiac electrical activity within the cardiac tissue. Optionally, based on the identified cardiac electrical activity, tissue within the heart may be ablated or otherwise treated.
