Cardiopulmonary, behavioral, and psychological risk factors generate electrical and structural alterations of the atria that promote reentry and wavebreak. These culminate in fibrillation once atrial ectopic beats set the arrhythmia process in motion. There is growing evidence that chronic stres...

For patients with atrial fibrillation, percutaneous left atrial appendage closure (LAAC) emerged as a valid alternative to oral anticoagulation. This activity reviews the evaluation, indications/contraindications, pre/post-procedural management of percutaneous LAAC and highlights the role of the interprofess...
Atrial fibrillation (AF) has strong associations with other cardiovascular diseases, such as heart failure (HF), coronary artery disease (CAD), valvular heart disease, diabetes mellitus (DM), and hypertension. It is characterized by an irregular and often rapid heartbeat (see the first image belo...

Atrial arrhythmias, including atrial fibrillation, in the setting of congenital heart disease (CHD) are epidemiologically and mechanistically different from those encountered in the general population. These arrhythmias occur at younger ages in patients
The molecular mechanisms underlying atrial fibrillation (AF), the most common form of arrhythmia, are poorly understood and therefore target-specific treat

These changes in ion channel physiology and increased extracellular fibrosis are believed to potentiate atrial myocardial substrate-driven reentry. When The safety of atrial fibrillation ablation When performed by experienced operators, catheter ablation of AF is not a very high-risk procedure. As ...
