Late gadolinium enhancement magnetic resonance imaging (LGE MRI) is commonly used
to visualize and quantify left atrial (LA) scars. The position and extent of LA scars provide …

Changes in atrial size and function have historically been considered a surrogate marker of
ventricular dysfunction. However, it is now recognized that atrial cardiomyopathy (ACM) may …

Atrial fibrillation (AF) is the most frequent arrhythmia and is associated with substantial
morbidity and mortality. Pathophysiological aspects consist in the activation of pro-fibrotic …

Background Atrial fibrillation (AF) is associated with circulating inflammation. Short-chain
fatty acids (SCFAs) derived from gut microbiota (GM) regulate leukocyte function and inhibit …

Atrial cardiomyopathy (ACM) represents a constantly evolving concept, with increasing
importance in contemporary research and clinical practice. A better understanding of the …

Atrial fibrillation (AF) is the primary cause of ischaemic stroke and transient ischaemic attack
(TIA). AF is associated with a high risk of recurrence, which can be reduced using optimal …

Aims To quantitatively investigate the impact of left atrial geometric remodeling on atrial
fibrillation recurrence after catheter ablation. Methods A retrospective analysis of 105 …

Atrial fibrillation (AF) has been described in COVID-19 patients. Recently, some case reports
and US pharmacovigilance analyses described AF onset as a rare adverse event following …

Background: This study aimed to evaluate the morphometrical features of left atrial
appendage (LAA) in patients with atrial fibrillation, subjected to left atrial appendage …

In 10% of ischemic strokes, non-valvular atrial fibrillation (NVAF) is detected retroactively.
Milder, or even asymptomatic forms of NVAF have shown high mortality, thrombotic risk, and …
