Prospective randomized comparison of irrigated-tip versus conventional-tip catheters for ablation of common flutter.


BACKGROUND Radiofrequency (RF) ablation of common flutter requires the creation of a complete ablation line to produce bidirectional conduction block in the cavotricuspid isthmus. An irrigated-tip ablation catheter has been shown to be effective in patients in whom conventional ablation has failed. This randomized study compares the efficacy and safety of… (More)
