Comparison between the novel diamond temp and the classical 8-mm tip ablation catheters in the setting of typical atrial flutter

摘要

Abstract Purpose Radiofrequency (RF) catheter ablation is widely accepted as a first-line therapy for cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL). The novel DiamondTemp (DT) catheter with temperature feedback during RF ablation has been released recently on the market. The purpose of this study was to evaluate the impact of DiamondTemp (DT) technology on ablation efficiency during AFL.Methods In this single-center study, 30 consecutive patients with typical AFL indicated to ablation of CTI were included. The first 15 patients underwent CTI ablation using 8-mm tip catheter, and the following 15 patients underwent temperature-controlled RF ablation using DT catheter. The endpoints were number and mean total duration of RF applications, mean temperature reached in the setting of CTI, procedural times, and fluoroscopy times.Results There were no significant differences between the two groups concerning baseline characteristics. Mean duration of the each application (71.5?s?±?30.6 vs 12.4?s?±?13.2, p value?
