Purpose: Several predictive scores for atrial fibrillation (AF) recurrence after AF ablation have been developed. We compared the predictive value of seven previously described risk scores ((CHADS2 and CHA2DS2-VASC, HATCH, APPLE, CAAP-AF, BASE-AF2, MB-LATER) for prediction of AF recurrence risk at 12 months after AF ablation in our patient cohort. Further, we aimed to identify additional variables to predict recurrences after AF ablation.
Methods: We used data from our digital AF ablation registry to compare the previously published scores in an independent cohort (n?=?883, 50.8% with paroxysmal AF). The scores were chosen based on earlier publications and availability of relevant data.
Results: The BASE-AF2 (AUC 0.630, p?
Conclusion: Despite numerous available scores, predicting recurrences after AF ablation remains challenging. New predictors are needed, potentially based on interventions, as well as novel genetic, functional and anatomic parameters.
