We are facing a new challenge: will imaging be the resolutive tool or will new mapping catheters and mapping system together with mathematical simulation solve this rebus? Clinical imaging will always remain attractive, particularly for elective cases and may add decisive information to best plan an ablation strategy: it represents a great tool in the hands of the electrophysiologist; however, as electrophysiologists, the imaging we should pursue is electrical – the depiction of the entire reentry circuit remains the sole proof of the target to ablate.
