Abstract

Background: Radiofrequency (RF) ablation of typical atrial flutter (AFL) is a well-established method of treatment. Although its efficacy is high, a search for new, more effective techniques is continuing. These new methods include modern systems for electro-anatomical mapping and new types of ablating electrodes such as cooled-tip or dual-sensor catheters.
Aim: To assess the efficacy of RF ablation of typical AFL with the use of electro-anatomical mapping system CARTO and to compare the effectiveness of various ablating catheters.
Methods: The study group consisted of 60 consecutive patients who underwent RF ablation of typical AFL with the use of the CARTO system. In 35 patients standard ablating electrodes were used, in 15 - cooled-tip catheters (Thermo-Cool), and in 10 - Dual-Sensor catheters.
Results: Overall efficacy of RF ablation was 96.6%. In two procedures which occurred ineffective, standard ablating electrodes were used. In 4 (6.6%) patients a recurrence of AFL was noted - also these patients had RF ablation performed with the use of standard ablating electrodes. None of the patients had procedure-related complications.
Conclusions: RF ablation of typical AFL with the use of electro-anatomical system CARTO is effective, safe and associated with reduced fluoroscopy time. The use of cooled-tip or dual sensor ablating electrodes further enhances efficacy of the procedure.
