Introduction: The aim of this prospective randomized study was to compare the efficacy and safety of catheter ablation (CA) versus surgical ablation (SA) in the treatment of paroxysmal and persistent AF after failed initial pulmonary vein isolation procedure.
Methods And Results: Patients with a history of symptomatic AF after a previous failed first ablation procedure were eligible for this study. Patients were randomized to CA (n = 32) or SA (n = 32) redo ablation.
Aim: Catheter ablation of paroxysmal atrial fibrillation (PAF) is associated with an important risk of early and late recurrence, necessitating repeat ablation procedures. The aim of this prospective randomized patient-blind study was to compare the efficacy and safety of cryoballoon (Cryo) versus radiofrequency (RF) ablation of PAF after failed initial RF ablation procedure.
Methods: Patients with a history of symptomatic PAF after a previous failed first RF ablation procedure were eligible for this study.
Background: Recurrences are common within the first months following atrial fibrillation (AF) ablation. However, prior studies using only intermittent ECG recording have not shown a powerful correlation with ultimate response.
Objective: The purpose of this study was to use continuous AF monitoring with an implanted monitor to assess the AF burden measured continuously during the first months postablation and the relationship to subsequent AF recurrences.
