Atrioventricular node ablation and permanent ventricular pacemaker implantation without fluoroscopy: use of an electroanatomic navigation system.

Non-fluoroscopy AV ablation and pacemaker implantation. Fluoroscopic guidance is the standard tool used for transvenous pacemaker implantations and for electrophysiological and ablation procedures. It implies X-ray exposure, occasionally with high dose of radiation for the patient and operator. We describe the case of a 47-year-old man with uncontrollable permanent atrial fibrillation to whom ablation of the AV conduction and a permanent ventricular pacemaker implantation were successfully performed under the guidance of an electroanatomic navigation EnSite NavX system and with no use of fluoroscopy. This case illustrates the stand-alone use of one of the new non-fluoroscopic navigation systems for a complete procedure such as AV ablation and pacemaker implantation.
