Atrial fibrillation is the most common arrhythmia encountered in clinical practice affecting
both patients' survival and well-being. Apart from aging, many cardiovascular risk factors …

Atrial fibrillation (AF) is characterized by disorganized rapid atrial electrical activity, which
leads to impaired atrial function, adverse hemodynamic effects, and increased …

Background Observational studies report that obstructive sleep apnea (OSA) is associated
with an increasingly remodeled atrial substrate in atrial fibrillation (AF). However, the impact …

Objectives: This study sought to determine the long-term right atrial (RA) electrical and
structural changes in a subgroup from the CAMERA-MRI (Catheter Ablation Versus Medical …

Background Few studies have investigated right atrial (RA) remodeling in heart failure (HF)
with preserved ejection fraction (HFpEF). This study sought to characterize the RA …

Aims Unipolar voltage (UV) mapping is increasingly used for guiding ablative therapy of
atrial fibrillation (AF) as unipolar electrograms (U-EGMs) are independent of electrode …

Background Atrial remodelling has been poorly investigated in atrial fibrillation (AF), and few
studies have focused on biatrial remodelling. Aim To evaluate right atrial (RA) and left atrial …

Right atrial (RA) structural and functional evaluations have recently emerged as powerful
biomarkers for adverse events in various cardiovascular conditions. Quantitative analysis of …

Background Recurrence of atrial fibrillation (AF) after pulmonary vein isolation (PVI) is
associated with left atrial (LA) remodeling; however, its association with right atrial (RA) …

Background There is limited data on the scar burden in patients with atrial fibrillation (AF). In
this study, we sought to evaluate the presence and extent of an abnormal left atrial (LA) …
