Background: Percutaneous endocardial left atrial appendage occlusion (LAAO) is an
alternative therapy for stroke prevention in patients with atrial fibrillation who are poor …

Large left atrium (LA) and LA appendage (LAA) dysfunction are known to relate to
cardiogenic thromboembolism, so the present study investigated the relation of the atrial …

The role of transesophageal echocardiography (TEE) in thromboembolic risk stratification in
atrial fibrillation (AF) has not been established. Left atrial appendage contractile dysfunction …

Atrial fibrillation is the most common cardiac arrhythmia and its prevalence is constantly
increasing. The main complications related to atrial fibrillation are death and major stroke …

Objectives: Several studies exist on the left atrial appendage function (LAA) in permanent
atrial fibrillation (AF). However, knowledge about the right atrial appendage (RAA) function …

To assess right atrial appendage (RAA) flow and its possible relationship to left atrial
appendage (LAA) flow in chronic nonvalvular atrial fibrillation (AF), transesophageal …

Non-valvar atrial fibrillation confers a substantial risk for stroke and thromboembolism which
is estimated to be between 4-5% and 12% per year depending on associated risk factors.'2 …

Thrombogenesis in the left atrial appendage (LAA) has been related to the special
morphology of this cavity and to its size and degree of dysfunction. However, no study has …

Seventy-eight patients with chronic nonrheumatic atrial fibrillation were studied by
transesophageal echocardiography with regard to the left atrial appendage function and its …

Background Cerebral thromboembolism is a potentially devastating complication of atrial
fibrillation (AF) and atrial flutter (AFl). The use of transesophageal echocardiogram (TEE) …
