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 blood flow velocity patterns within the left atrial appendage were studied by
transesophageal color flow imaging and pulsed Doppler in 84 patients. At the time of the …

BACKGROUND The predilection of the left atrial appendage (LAA) for thrombus formation
has long been known. METHODS AND RESULTS We prospectively studied the two …

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 …

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 …

The characteristics and clinical implications of left atrial appendage (LAA) flow have not
been clearly analyzed. Thirty-nine consecutive patients underwent a transesophageal …

Recent evidence suggests that left atrial (LA) appendage velocities may provide clues to the
thrombogenic potential of this structure. Pulsed Doppler evaluation of LA appendage flow …

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 …

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

Objective To compare the value of current transthoracic echocardiographic systems and
transoesophageal echocardiography for assessing left atrial appendage function and …
