Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: The investigators retrospectively analyzed patients who underwent catheter ablation of AAF and compared procedural results between patients with ongoing tachycardia when starting the procedure and patients with induced AAF.
For this retrospective study, the investigators analyzed patients undergoing ablation of AAF between April 2018 and January 2021 that were identified from the ablation database at the West German Heart and Vascular Center, Essen. All patients were followed up in the outpatient clinic as part of the clinical standard routine or contacted by telephone to assess the occurrence of clinical recurrence of any arrhythmia. In case the documentation was not performed at the institution, relevant documents and ECGs were requested and reviewed.
This single-center cohort study was conducted at the University Hospital Essen, Germany, in accordance with the Declaration of Helsinki and its amendments and was approved by the institutional review board of the University of Essen (number 21-10341-BO). Written informed consent was obtained from all study participants.
The primary study endpoint was to evaluate the outcome of patients with induced AAF in comparison to patients with ongoing AAF when starting the procedure. Furthermore, the investigators analyzed the type of recurrence during follow-up as well as the occurrence and results of repeat ablations at the institution. The investigators also evaluated if the recurrent AAF form was the same or de-novo compared to the AAF during previous procedure.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Induced atypical atrial flutter
Sinus rhythm when starting the procedure, so atypical atrial flutter had to be induced.
Induction of atypical atrial flutter
Electrophysiological study with induction of atypical atrial flutter. When the induction was successful, ablation of arrhythmia was performed similar to the control group.
Ongoing atrial flutter
Atypical atrial flutter was already ongoing when starting the procedure.
No interventions assigned to this group
