During the past decade, catheter ablation of atrial fibrillation (AF) has evolved rapidly from
an investigational procedure to its current status as a commonly performed ablation …

Background—Complex-fractionated atrial electrograms and atrial fibrosis are associated
with maintenance of persistent atrial fibrillation (AF). We hypothesized that pulmonary vein …

Background: The use of intracardiac electrograms to guide atrial fibrillation (AF) ablation has
yielded conflicting results. Objectives: The authors evaluated the usefulness of …

Abbreviations: 3D, three-dimensional; AF, atrial fibrillation; AP, accessory pathway; ARVC,
arrhythmogenic right ventricular cardiomyopathy; AT, atrial tachycardia; AVB, atrioventricular …

Objectives: This study sought to evaluate the relationship between fibrosis imaged by
delayed-enhancement (DE) magnetic resonance imaging (MRI) and atrial electrograms …

Curved surfaces, complex geometries, and time-dynamic deformations of the heart create
challenges in establishing intimate, nonconstraining interfaces between cardiac structures …

Background: Mounting evidence shows that localized sources maintain atrial fibrillation (AF).
However, it is unclear in unselected “real-world” patients if sources drive persistent atrial …

Background—The foundation for successful arrhythmia ablation is the map** of electric
propagation to identify underlying mechanisms. In atrial fibrillation (AF), however, map** …

Low atrial endocardial bipolar voltage, measured during catheter ablation for atrial
fibrillation (AF), is a commonly used surrogate marker for the presence of atrial fibrosis. Low …
