The management of atrial arrhythmia recurrence during repeat catheter ablation procedure is unclear despite persistent pulmonary vein isolation. It should be clarified whether an induced non-PV trigger-based (mechanistic) ablation approach more focusing on low-voltage zones is more effective compared to an empirical ablation of low-voltage zones via linear lesions during repeat ablation procedures. The operators should catch all triggers if possible rather than messing with the substrate.
