Abstract
The AV nodal reentrant tachycardia (AVNRT) is, for the vast majority of EP labs around the world, the most common arrhythmia substrate to ablate; if it is true that little fluoroscopy is needed to ablate a slow pathway, as the number of cases outweighs by far more complex substrates (where fluoroscopy reduction could have a greater individual exposure impact), starting a fluoroscopy-free approach should start in everyday cases, to then move to complex arrhythmias.
The amount of exposure to fluoroscopy is highly dependent on multiple variables, such as operator experience and complexity of the arrhythmia substrate. As exposure to radiation during such procedures increases the lifetime risk of fatal malignancies, skin injuries, and cataract, it poses a palpable hazard to both patients and medical staff.
We hope at the end of this chapter to have convinced the readers that there are only advantages to the use of 3D mapping systems to ablate any AVNRT. We present the data with emphasis on how to perform a procedure without fluoroscopy.
