ENHANCING EFFICIENCY OF REPEAT ABLATION BY MERGING CURRENT AND PREVIOUS MAPS

摘要

A method for cardiac treatment, which includes acquiring and saving an initial map of a chamber of a heart of a patient in an initial ablation procedure, with locations of ablation lesions marked on the initial map. In preparation for a redo ablation procedure, subsequent to the initial ablation procedure, a current map of the chamber is acquired, the initial map is registered with the current map, and the locations of the ablation lesions from the registered initial map are marked and displayed on the current map.
