Background: Although atrial fibrillation (AF), a common arrhythmia, frequently presents in
patients with underlying valvular disease, its hemodynamic contributions are not fully …

Aims Reduction of left atrial appendage (LAA) flow velocity (FV) is a risk factor for thrombus
formation and increases the risk of stroke in patients with atrial fibrillation (AF). Furthermore …

Atrial fibrillation (AF) is a common comorbidity in left ventricular assist device (LVAD)
patients and has been identified as a risk factor for thromboembolic stroke. Blood stagnation …

Background: The shape of the left atrial appendage (LAA) might affect thrombus formation.
The chicken wing-type LAA (CW) has been reported as unlikely to influence stroke events in …

Atrial fibrillation (AF) is nowadays the most common human arrhythmia and it is considered
a marker of an increased risk of embolic stroke. It is known that 99% of AF-related thrombi …

Disruptions to left atrial (LA) blood flow, such as those caused by atrial fibrillation (AF), can
lead to thrombosis in the left atrial appendage (LAA) and an increased risk of systemic …

In recent years, there has been a move from monoventricular or biventricular models of the
heart, to more complex models that incorporate the electromechanical function in all 4 …

To examine changes in left atrial appendage flow velocity patterns in relation to left atrial
pressures during sinus rhythm, transesophageal echocardiography and cardiac …

Aims To assess the relation between left atrial appendage (LAA) morphology and
echocardiographic flow pattern of the LAA by means of two-and three-dimensional …

Although several flow patterns in the left atrial appendage have been described, mechanical
determinants of its function have not been elucidated in human beings. We attempted to …
