Abstract

Introduction: LocaLisa is a novel system for anatomical mapping. It enables an assessment of the three-dimensional position of electrodes within cardiac chambers without fluoroscopy. With this technique it may be possible to reduce radiation exposure during catheter-based ablation procedures. Aim: To evaluate the efficacy and safety of ablation procedures performed using the LocaLisa mapping system in patients with atrioventricular nodal reentrant tachycardia (AVNRT). Methodology: This study evaluated the course of the first 26 ablations performed using the LocaLisa system (studied group). The control group involved 30 consecutive patients with AVNRT treated with the conventional ablation technique that was routinely used prior to the introduction of the novel system into clinical practice. Results: In the studied group procedural duration was 72.4±24.9 minutes, in the control group 80.1±18.2 minutes (NS). However, radiation exposure was significantly lower in the examined group - 74.4±109.2 mGy compared to 184.8±59.9 mGy in the control group (p
