Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Clinical indication for ablation: a) symptoms (palpitations, dizziness, syncope, breathlessness, derangement, heart failure), tachymiopathy, b) poor heart rate control, or c) recurrence after electrical cardioversion or failure of one antiarrhythmic drug.
* Informed consent.
1. Patients will be enrolled if LAFL is clinically suspected but finally randomized if this mechanism is established by electrophysiologic evaluation according to the criteria stated above.
Exclusion Criteria
* Previous linear ablation in the LA except for pulmonary vein isolation.
* Absolute contraindication for oral anticoagulation.
* Stroke or acute coronary syndrome less than 3 months before ablation.
* Complex congenital heart disease.
