Main Findings
The main findings of this study were that patients who underwent
CF-guided ablation less frequently developed ER than those who underwent
non-CF-guided ablation. Moreover, all patients in the CF group with ER
occurring in the 3rd month developed LR, although
22.2% of patients in the Non-CF group who had ER in the
3rd month were free-from LR during 2-year follow-up
period. These findings suggest that ER occurring in the
3rd month is a specific risk factor for LR and that an
early redo-procedure may be reasonable in patients who underwent PVI
using CF technology.
