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...

Atrial fibrillation is a supraventricular tachyarrhythmia and the most common kind. It is caused by rapid, uncontrolled atrial contractions and uncoordinated ventricular responses.
Atrial fibrillation (AF) is the most common arrhythmia in the elderly population and it is associated with a four-fold to five-fold increased risk of thromboembolic events. It was not until the mid-1950s that the left atrial appendage (LAA) was identified as the main location of thrombus fo...

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 is considered to be recurrent when a patient has two or more episodes. If recurrent AF terminates spontaneously, it is designated as paroxysmal. Some patients with paroxysmal AF, typically younger patients, have been found to have distinct electrically active foci within their pulm...

The molecular mechanisms underlying atrial fibrillation (AF), the most common form of arrhythmia, are poorly understood and therefore target-specific treat
