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.
