Background: The thickness and motion of the Interatrial Septum (IAS) possibly serves as indicators of both structural and functional remodeling of left atrium. This study aims to use transesophageal echocardiography (TEE) to assess IAS motion in non-valvular atrial fibrillation (NVAF) and investigate its correlation with the risk of spontaneous echo contrast (SEC) and thrombus (TH).
Methods: We conducted a cross-sectional study on 318 patients with NVAF who underwent transthoracic echocardiography and TEE.

Article Synopsis
- The study investigates the link between traditional vascular risk factors and cervical artery dissection, particularly focusing on older patients.
- Using data from Medicare beneficiaries, the research identifies several risk factors, including hypertension, alcohol use, and coronary artery disease, that are associated with an increased likelihood of developing cervical artery dissection.
- The findings suggest that older individuals with certain vascular conditions are at a higher risk, indicating the need for further research on these associations.

Antiphospholipid syndrome (APS) is characterized by hypercoagulability, manifesting as venous or arterial thrombosis, and pregnancy-related complications, such as fetal loss, pre-eclampsia, and eclampsia. These conditions occur in the presence of antiphospholipid antibodies (aPL), including anticardiolipin antibodies (aCL) and/or a positive lupus anticoagulant (LA) test. Antiphospholipid syndrome (APS) can manifest as a primary, isolated condition or be associated with connective tissue diseases, such as systemic lupus erythematosus (SLE).

Transesophageal echocardiography (TEE) is the standard method for diagnosing left atrial appendage (LAA) hypercoagulability in patients with atrial fibrillation (AF), which means LAA thrombus/sludge, dense spontaneous echo contrast and slow LAA blood flow velocity (< 0.25 m/s). Based on machine learning algorithms, cardiac computed tomography angiography (CCTA) radiomics features were adopted to construct prediction models and explore a suitable approach for diagnosing LAA hypercoagulability and adjusting anticoagulation.

Background: Atrial fibrillation (AF) can lead to a decline in left atrial appendage (LAA) function, potentially increasing the likelihood of LAA thrombus (LAAT) and spontaneous echo contrast (SEC). Measuring LAA flow velocity through transesophageal echocardiography (TEE) is currently the primary method for evaluating LAA function. This study aims to explore the potential correlation between anterior mitral annular plane systolic excursion (aMAPSE) and LAA stasis in patients with non-valvular atrial fibrillation (NVAF).
