Conclusion
In this real-world de-identified EHR dataset of AF patients with CIEDs
undergoing catheter ablation, perceived treatment success varied
substantially with different definitions of minimally required AF
duration and the method of recurrence detection. The traditional metrics
of absolute recurrence or time to first AF recurrence following ablation
undervalues the efficacy of ablation when compared to the measure of AF
burden reduction, which is likely a more clinically relevant endpoint.
