Danish Evaluation of Early Catheter Ablation for Atrial Fibrillation in Patients With Heart Failure

Summary

The DanAblate-HF trial will investigate whether early catheter ablation treatment for atrial fibrillation in patients with heart failure is superior to standard treatment.

Eligibility

Inclusion Criteria:

   HF is defined as all of the below (all must apply)
   * Clinically assessed Heart Failure with Reduced Ejection Fraction (HFrEF)
   * An indication for initiation or ongoing guideline directed medical therapy for HFrEF, according to current Heart Failure guidelines
   * LVEF \< 50% at any point during the past 12 months

   AF is defined as one or more of the following:

   A. Symptomatic AF, documented by ECG, Holter of CIED

   B. Asymptomatic AF with one or more of the following:
   * Clinical indication for rhythm or rate control (documented by ECG, telemetry, Holter, CIED)
   * ≥2 ECG detected AF episodes within 3 months (on separate dates)
   * Holter detected AF with a continuous duration of more than 6 hours
   * CIED detected AF with continuous duration \>24 hours
2. 18 years ≤ Age \<80 years
3. Optimal medical therapy for HFrEF or planned/current uptitration in guideline directed medical therapy for HFrEF
4. Treatment with anticoagulation for stroke prevention, initiated according to guidelines for treatment of AF

6. Previous AF ablation/surgery
7. Reversible causes of AF (including, but not limited to, infection within 14 days, untreated thyroid disease, surgery)
8. Severe valvular disease
9. Acute myocardial infarction, cardiothoracic surgery or stroke within the past 3 months
