Atrial fibrillation is the most common sustained cardiac arrhythmia, which is associated with
a high risk of stroke and thromboembolism. Increasing evidence suggests that the …

The left atrial appendage (LAA) is derived from the left wall of the primary atrium, which
forms during the fourth week of embryonic development. It has developmental …

The LAA is the remnant of the embryonic left atrium, whereas the smooth-walled left atrium
originates from the primordial pulmonary vein and its branches. The LAA is largely …

The left atrial (LA) appendage is a common source of cardiac thrombus formation associated
with systemic embolism. Transesophageal echocardiography allows a detailed evaluation of …

Atrial fibrillation (AF) is the commonest sustained cardiac arrhythmia and is associated with
significant morbidity and mortality. There is plenty of evidence available to support the …

We evaluated the role of left atrial appendage (LAA) in the left atrial (LA) reservoir function
by assessing the changes in LA flow dynamics after LAA clamping during cardiac surgery …

Conversion of atrial fibrillation and flutter to sinus rhythm results in a transient mechanical
dysfunction of atrium and atrial appendage, termed atrial stunning. Atrial stunning has been …

The left atrial appendage (LAA) is the main source of thromboembolism in patients with non-
valvular atrial fibrillation (AF). As such, the LAA can be the target of specific occluding device …

Atrial fibrillation (AF) is the most-common arrhythmia in the elderly population (age> 65
years). The left atrial appendage (LAA) is the main location of thrombus formation …

Objectives. The purpose of this study was to identify the effects of altered loading conditions
on left atrial appendage flow velocities. Background. Although studies have suggested that …
