Repeat procedure
The redo procedures implemented long sheaths (n=5, 63%), and irrigated-tip catheters (n=4, 50%). The second procedure was performed at an average of 3 years post-initial ablation (11.5±3 vs 14.6±1.9). The source of energy was radiofrequency in all the redo procedure, and 3 (38%) incorporated irrigated-tip catheters.
