36 Derivation of a prediction model for the optimization of patient selection for catheter ablation of atrial fibrillation: the AF-FREEDOM score.

Background: Catheter ablation is the most effective treatment option for restoring sinus rhythm and potentially eradicate or reduce the overall burden of atrial fibrillation (AF). Success rates as high as 80% have been described for patients with paroxysmal AF, but for other forms of this arrhythmia, or for patients with specific comorbidities success rates are known to be well below 50%. This therapy is associated with costs and non-negligible procedural complications. Development of a risk predictive model to identify patients with higher chances of procedural success could be of interest to improve the risk-benefit, and cost-effectiveness of this treatment approach.
