Objective To evaluate the feasibility and effect of three-points ablation approach in in treatment of typical atrial flutter guided by CARTO. Methods Twenty-six patients with typical atrial flutter diagnosed by ECG and electrophysiological study (EPS) were enrolled in this study. Activation sequence mapping and linear ablation were performed in 11 patients (conventional group). Three-points guided linear ablation with CARTO system was performed in another 15 patients (three-points group) . Results There was no significant difference in the success rate between the two groups. Both the procedure and fluoroscopic time in three-points group were significantly shorter than that in conventional group [(72.66 ± 29.82) vs (102.52 ± 32.61) min; (4.26 ± 2.76) vs (7.32 ±3.16) min] . Conclusions The three-points ablations approach is as safe and effective as conventional ablation approach in treatment of typical atrial flutter; however, the former can significantly shorten the procedure time and fluoroscopy time.
