Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by irregular and rapid
electrical activity in the atria, leading to ineffective contraction and poor blood flow. More …

BACKGROUND: Hemostasis in the left atrial (LA) appendage (LAA) is an important cause in
the formation of thrombi. Determination of the LAA flow velocity (LAAV) could be a …

Atrial fibrillation (AF), the most common human arrhythmia, is a marker of an increased risk
of embolic stroke. However, recent studies suggest that AF may not be mechanistically …

The hypotheses of this prospective study were that (1) left atrial appendage (LAA) blood flow
velocities can be recorded in cats with myocardial disease by transthoracic Doppler …

Background and objectives The left atrial appendage (LAA) is the most common region for
thrombus formation in atrial fibrillation (AF). Morphological parameters such as shape, size …

The aim of this study was to evaluate left atrial deformations using speckle tracking
echocardiography for predicting left atrial appendage (LAA) thrombus in patients with …

OBJECTIVES: We sought to detect cardiac thrombi by transthoracic and transesophageal
echocardiography in patients with Chagas' cardiomyopathy and to determine the …

Discontinuation of anticoagulation therapy after catheter ablation (CA) for atrial fibrillation
(AF) remains controversial. While decreased left atrial appendage flow velocity (LAAFV) …

Background Atrial fibrillation (AF) is associated with a 5‐fold increased stroke risk. While
most patients with AF warrant anticoagulation, optimal treatment remains uncertain for …

Objective: The aim of this study was to determine the relationship of left atrial appendage
(LAA) mechanics assessed using 2-dimensional (2D)-strain analysis of the gray scale …
