Ablation of Posteroseptal Accessory Pathways
Abstract Posteroseptal accessory pathways (APs) are actually not septal but reside in a complex region bordering the right atrium, right ventricle, left ventricle, left atrium and coronary sinus and its…
Catheter Ablation of Superoparaseptal (Anteroseptal) and Midseptal Accessory Pathways
Abstract Safe and successful catheter ablation of superoparaseptal (previously called anterior septal ) and midseptal accessory pathways (APs)—those for which ablation poses the highest risk of damaging the normal conduction…
Substrate-Based Ablation for Atrial Fibrillation
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…
Pulmonary Vein Isolation for Atrial Fibrillation
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…
Ablation of Nonpulmonary Vein Triggers
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…
Epicardial and Endocardial Hybrid Ablation for Atrial Fibrillation
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…
Atrioventricular Junction Ablation for Heart-Rate Control of Atrial Fibrillation
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…
Ablation of Atrial Fibrillation Drivers: Focal Impulse and Rotor Modulation
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),…
Ablation of Cavotricuspid Isthmus–Dependent Atrial Flutters
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,…
Cardiac Anatomy for Catheter Mapping and Ablation of Arrhythmias
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…
