The LAA is the remnant of the embryonic left atrium, whereas the smooth-walled left atrium
originates from the primordial pulmonary vein and its branches. The LAA is largely …

The left atrial appendage (LAA) is a major source of emboli responsible for cardioembolic
stroke (CES). We hypothesized that there could be differences in the morphologic and …

Risk of Stroke/TIA in Patients With Atrial Fibrillation. Introduction: Most strokes in patients
with atrial fibrillation (AF) arise from thrombus formation in left atrial appendage (LAA). Our …

Objectives: This study investigated the left atrial appendage (LAA) by computed tomography
(CT) and magnetic resonance imaging (MRI) to categorize different LAA morphologies and …

Background—In patients with atrial fibrillation (AF), most thrombus forms in the left atrial
appendage (LAA). However, the relation of LAA morphology with LAA thrombus is unknown …

OBJECTIVES: We sought to define right atrial appendage (RAA) anatomic and functional
parameters in a consecutive series of participants and to compare these measures with left …

Background: The shape of the left atrial appendage (LAA) might affect thrombus formation.
The chicken wing-type LAA (CW) has been reported as unlikely to influence stroke events in …

Background and Purpose—A noninvasive technique of visualizing the left atrial appendage
(LAA) and its thrombus in patients with atrial fibrillation would be of great interest. This study …

Why Is Left Atrial Appendage Morphology Related to Strokes? Background A specific
morphology of left atrial appendage (LAA) has been reported to be related to stroke in …

BACKGROUND: Strokes develop even in patients with low CHADS2 scores, and the left
atrial appendage (LAA) is the embolic source 90% of the time. We focused on the LAA …
