Abstract Atrial substrate modification is required for a successful outcome in a minority of patients with paroxysmal atrial fibrillation (AF), and in most patients with persistent AF. Substrate modification is…
Abstract Pulmonary vein isolation (PVI) represents the cornerstone of current catheter ablation techniques for the treatment of atrial fibrillation (AF), with significantly improved efficacy compared with antiarrhythmic drug therapy as…
Abstract Nonpulmonary vein (non-PV) “triggers” can be identified in 10% to 33% of unselected patients with atrial fibrillation (AF). Compared with paroxysmal AF, the incidence of non-PV foci is higher…
Abstract Simultaneous endocardial and epicardial ablation, a hybrid therapy for atrial fibrillation, combines the independent strengths of surgical and catheter-based ablation. Catheter technology utilizes electrical and anatomic mapping of atrial…
Abstract Mapping uses a combined anatomy- and electrogram-guided approach. The right-sided approach target is just proximal to or below the His bundle electrode position on the fluoroscopic view, or at…
Abstract Approaches for the ablation of atrial fibrillation (AF) have changed rapidly in the past two decades and are focused on eliminating triggers near and from the pulmonary veins (PV),…
Abstracts Cavotricuspid isthmus (CTI)-dependent atrial flutter (AFL) is a common atrial arrhythmia, often occurring in association with atrial fibrillation, that may cause significant symptoms because of a rapid ventricular response,…
Abstract Cardiac anatomy remains a cornerstone for successful and safe interventional treatment for cardiac arrhythmias. The importance of appreciating detailed anatomy and correlating the specifics real time with fluoroscopy and…
Abstract Ablation of persistent and long-standing persistent atrial fibrillation (AF) is a potentially complex procedure that carries a lower success rate than ablation for paroxysmal AF. Predictors of recurrence include…
Abstract Cryoballoon ablation is a safe and predictable toolset to generate a reliable large-area pulmonary vein antral modification for the treatment atrial fibrillation. Its reproducibility amongst a wide range of…
