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�…

Atrial fibrillation (AF) is the most common sustained cardiac rhythm disturbance, increasing
in prevalence with age. AF is often associated with structural heart disease, although a�…

Objectives: We sought to test the hypothesis that complex fractionated electrograms (CFAEs)
recorded during atrial fibrillation (AF) could be used as target sites for catheter ablation of�…

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

Background—The pulmonary veins (PVs) and surrounding ostial areas frequently house
focal triggers or reentrant circuits critical to the genesis of atrial fibrillation (AF). We�…

The writing committee consisted of acknowledged experts in the field of CMR, as well as a
liaison from the ACCF Task Force on Clinical ECDs, the oversight group for this document�…

Background—The purpose of this study was to conduct a worldwide survey investigating the
methods, efficacy, and safety of catheter ablation (CA) of atrial fibrillation (AF). Methods and�…

The American Heart Association makes every effort to avoid any actual or potential conflicts
of interest that may arise as a result of an outside relationship or a personal, professional, or�…

Background—The pulmonary veins (PVs) have been demonstrated to often play an
important role in generating atrial fibrillation (AF). The purpose of this study was to determine�…
