Anticoagulants such as warfarin are recommended for patients with atrial fibrillation (AF) to
decrease stroke risk associated with thrombus formation in the left atrium (LA). In a subgroup …

BACKGROUND: There is no clear consensus about antithrombotic treatment in atrial
fibrillation (AF) patients at low-intermediate thromboembolic risk. Transesophageal …

Background: Transesophageal echocardiography (TEE) is the first technique of choice for
evaluating the left atrial appendage flow velocity (LAAV) in clinical practice, which may …

Background: This study was planned to assess whether strain rate (Sr) and strain (S)
echocardiography is a useful method for functional assessment of the left atrial appendage …

Aim: We validated transthoracic echocardiographic measurements of left atrial appendage
flow velocity by comparing them with transoesophageal echocardiographic measurements …

The three‐dimensional (3D) structures of the right atrial appendage (RAA) and left atrial
appendage (LAA) were compared to clarify why thrombus formation less frequently occurs in …

Background It is sometimes difficult to make a diagnosis of cardioembolic stroke in the stroke
care unit, because of the splashing and vanishing of the intracardiac source of the emboli on …

Objective: We evaluated the changes in fibrinolytic activation markers before starting
anticoagulation, at 1 and 6 months following the introduction of anticoagulant therapy …

Background The left atrial appendage (LAA) flow velocity is an important factor for thrombus
formation in patients with non-valvular atrial fibrillation (NV-AF). Recently, the relation of …

Objective: To study the left atrial appendage (LAA) function and potential for embolization in
severe mitral stenosis (MS). Background: Patients with MS and atrial fibrillation or in sinus …
