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

The increasing prevalence of stroke and atrial fibrillation is a stimulus for new therapeutic
strategies and also warrants a review of imaging modalities of the most important source of …

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 …

The “elimination” of the left atrial appendage (LAA) seems to be an attractive alternative to
oral anticoagulation in the treatment of atrial fibrillation, especially in patients with …

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 …

Aims: Assess the value of peak atrial systolic mitral annular velocity (A ann) measured by
Doppler tissue echocardiography to quantify left atrial systolic function. Methods: We studied …

For many years, the left atrial appendage (LAA) was considered a dormant embryological
remnant; however, it is a structurally complex and functional organ that contributes to cardiac …

Background: Closure of the fibrillating left atrial appendage (LAA) has been recommended
during valve surgery to decrease the risk of arterial embolism. However, patients undergoing …

For long, it was believed that the left atrial appendage (LAA) was a vestigial structure ea
structure which apparently did not have any meaningful function in normal life and could be …

Spontaneous echo contrast (SEC) indicates blood stasis in cardiac chambers and major
vessels, and is a known precursor of thrombus formation. Transesophageal …
