Pulmonary vein isolation (PVI) is a well-established therapy in patients with atrial fibrillation who remain symptomatic under optimal medical therapy. Since the original description of atrial fibrillation ablation, numerous studies have demonstrated the superiority of catheter ablation over pharmacological therapy for maintenance of sinus rhythm in patients with both paroxysmal and persistent atrial fibrillation. However, up to 70% of patients present with recurrence of atrial fibrillation after PVI. Therefore, identifying ideal candidates is an unmet clinical need. Nevertheless, the complex relationship between left atrial structure and function, electrical burden of atrial fibrillation and stroke risk is not well understood. Furthermore, progression of atrial remodeling has been shown to occur even over 12 months in patients with high-burden paroxysmal or persistent AF. The purpose of our article to provide an overview of clinical applicability of echocardiography methods performed before PVI.
