Remote magnetic navigation for ventricular ablation: did the machine win this round?

Excerpt

Remote magnetic navigation has been available as a tool for mapping and ablation for well over a decade. In that period of time, it has shown to be useful in nearly every type of ablation procedure from the most simple to the most complex [1‐3]. Some operators prefer the system for atrial fibrillation ablation, others for ventricular tachycardia ablation, and some use it for any ablation. Despite numerous publications showing reductions in fluoroscopic exposure and the obvious benefits of not wearing lead and standing tableside for hours, remote magnetic navigation has not become the standard of care in the world [4]. Most publications appear to show similar success rates, and many show favorable complication rates [5‐7]. So what is the limitation to universal acceptance? In addition, many centers have purchased the system, yet it sits unused. Why would a physician give up a more comfortable procedure to perform an ablation wearing lead and being exposed to more radiation? …
