Discussion
To the best of our knowledge, this is the first study comparing the lesion metrics and safety profiles of two open irrigated ablation catheters from Abbott Medical (FlexAbilityTM SE and TactiCathTMSE), demonstrating that:
Compared to the TactiCathTM SE catheter, use of the FlexAbilityTM SE catheter leads to a significantly lower incidence of steam-pops, but produces smaller lesions with perpendicular catheter placement.
Regulation of RF-delivery due to the temperature-control setting was more frequently observed with the FlexAbilityTM SE catheter.
