The understanding of atrial fibrillation (AF) evolved from a sole rhythm disturbance towards
the complex concept of a cardiomyopathy based on arrhythmia substrates. There is …

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

Substrate Modification BIFA in AF Ablation Background Catheter ablation strategies beyond
pulmonary vein isolation (PVI) for treatment of atrial fibrillation (AF) are less well defined …

Aims Myocardial fibrosis is a hallmark of atrial fibrillation (AF) and its characterization could
be used to guide ablation procedures. Late gadolinium enhanced-magnetic resonance …

Atrial fibrillation (AF) is one of the most common tachyarrhythmias observed in the clinic and
is characterized by structural and electrical remodelling. Atrial fibrosis, an emblem of atrial …

Atrial fibrillation (AF) is the most common sustained arrhythmia in the population and is
associated with a significant clinical and economic burden. Rigorous assessment of the …

The mechanisms responsible for perpetuation of human persistent atrial fibrillation (AF) are
controversial and probably vary between individuals. A wide spectrum of mechanisms have …

Background Arrhythmias in cardiac amyloidosis (CA) result in significant comorbidity and
mortality but have not been well characterized. Objective The purpose of this study was to …

Atrial fibrillation (AF), the most commonly diagnosed arrhythmia, affects a notable
percentage of the population and constitutes a major risk factor for thromboembolic events …
