It was reported that approximately 90% of atrial ectopies trigger atrial fibrillation originate from the myocardium within the pulmonary vein and that catheter ablation of this origin can cure atrial fibrillation. In recent years, pulmonary vein isolation has become the standard of care. However, a second ablation is required in about 50-60% of cases of persistent atrial fibrillation. A number of additional treatment strategies have been proposed to improve outcomes, including ablation of the atrial fibrillation substrate. However, past prospective randomized studies have failed to demonstrate the efficacy of additional ablations that were previously thought to be effective. One factor has been the inadequate assessment of the atrial fibrillation substrate.
Recently, a system (CARTO FINDER) has become available that allows real-time assessment of electrical excitation within the atrium during atrial fibrillation, and is expected to provide high-performance assessment of the atrial fibrillation substrate. However, no randomized, prospective studies have been reported to date demonstrating that additional ablation of the atrial fibrillation substrate outperforms pulmonary vein isolation alone. Prospective, multicenter, randomized trials are needed to establish the evidence.

For initial catheter ablation of nonparoxysmal atrial fibrillation, patients will be randomized 1:1 to pulmonary vein isolation alone (Control group) or pulmonary vein isolation plus ablation of the atrial fibrillation substrate as guided by CARTOFINDER.
