  Introduction: The purpose of this study was to evaluate the feasibility of left bundle ablation guided by left bundle potential (LBP) and three dimensional mapping system (EnSite NavX system) in canine models. Methods and Results: The canines were sequentially allocated into two groups, left bundle branch ablation guided by LBP and either fluoroscopy or NavX system. An LBP (mean LBP-V 17.8 ± 2.6 ms; 13-21) was identified resulting in successful left bundle ablation in 9 dogs. The A:V electrogram ratio at the successful LBP ablation site was <1:10 in all 9 dogs successfully ablated. In two dogs, a similar potential (potential-V 24 or 28 ms, respectively) were identified, but radiofrequency energy application produced high degree or complete atrioventricular (AV) block. Left bundle branch ablation failed in the first three dogs. The .. View More»
