The left atrial appendage (LAA) is a finger-like extension originating from the main body of
the left atrium. Atrial fibrillation (AF) is the most common clinically important cardiac …

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 …

Objectives. The aim of this study was to determine the relations between spontaneous echo
contrast, left atrial appendage blood flow velocity and thromboembolism. Background. Left …

Aims: The aim of our study was to evaluate the prevalence of left atrial cavity and
appendage thrombosis in patients undergoing cardioversion for non-valvular atrial …

Stroke associated with atrial fibrillation (AF) is mainly due to embolism of thrombus formed
during stasis of blood in the left atrial appendage (LAA). Pathophysiologic correlates of …

Objectives: The aim of our study was to assess whether left atrial appendage (LAA) ligation
in patients undergoing mitral valve replacement is associated with the risk of future …

Objectives. This study was conducted to identify a subgroup of patients with nonrheumatic
atrial fibrillation with an increased risk for cardiogenic embolism by assessing left atrial …

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

Left atrial appendage (LAA) is frequently the site of thrombus formation in patients with
chronic atrial fibrillation (AF). Transesophageal echocardiography and hematologic studies …

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 …
