BACKGROUND: Although transesophageal echocardiography is the definitive test for the
detection of left atrial (LA) appendage thrombus, transthoracic echocardiography has yet to …

Data regarding left atrial (LA) and LA appendage anatomy and function among patients with
newly recognized atrial fibrillation (AF) who have not received longterm warfarin are …

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 …

Fifty-four patients with nonrheumatic atrial fibrillation (AF) were studied: 16 patients with
(group I) and 38 patients without (group II) documented systemic embolism …

Objectives. The purpose of this study was to investigate left atrial appendage size, function
and thrombus prevalence in patients with atrial “fibrillation-flutter.” Background. Thrombus …

OBJECTIVES This study sought to determine the incidence of incomplete ligation of the left
atrial appendage (LAA) during mitral valve surgery. BACKGROUND Ligation of the LAA to …

Background When stratifying thromboembolic risk to patients with atrial fibrillation (AF), left
atrial appendage (LAA) thrombus is currently the only echocardiographic index that …

Background Transesophageal echocardiography (TEE) is the gold standard for evaluation
of the left atrium and the left atrial appendage (LAA) for the presence of thrombi …

Transesophageal pulsed Doppler echocardiography was performed to examine changes
with age in the left atrial appendage flow velocity patterns in 50 normal subjects (15 to 80 …
