Cavotricuspid isthmus ablation using a catheter equipped with mini electrodes on the 8 mm tip: a prospective comparison with an 8 mm dumbbell-shaped tip catheter and 8 mm tip cryothermal catheter

摘要

The mini electrodes (ME) placed on the tip of the ablation electrode provide more precise local signal. We evaluated whether ME catheter was effective for the ablation of cavotricuspid isthmus (CTI)-dependent atrial flutter.
