Background: Intracardiac echocardiography (ICE) appears to be a potential alternative for percutaneous left atrial appendage occlusion (LAAO) to transesophageal echocardiography (TEE). Thus, a meta-analysis was performed comparing ICE vs. TEE for LAAO guidance.

We describe a 30-year-old Caribbean-Black woman with a clinical presentation suggestive of a transient ischemic attack (TIA) with no conventional cerebrovascular risk factors, albeit with a newly diagnosed quadricuspid aortic valve (QAV) with moderate aortic regurgitation (AR). Although QAV is a recognized congenital cardiac defect, its association with TIA remains elusive. This case highlights the importance of considering potential atypical etiologies, such as QAV, in the evaluation and management of young patients presenting with cerebrovascular events.

Background: The optimal imaging modality for selecting the device size in patients with atrial fibrillation undergoing one-stop left atrial appendage occlusion (LAAO) with concomitant pulmonary vein isolation (PVi) remains undefined. We compared preprocedural 3-dimensional computed tomography (3D CT) with intra-procedural transesophageal echocardiography (TEE) and left atrial appendage (LAA) angiography in guiding one-stage PVi and LAAO.

Methods: We measured the LAA ostium diameter using an interactive 3D CT system with a central line-based approach and compared these measurements with those from intra-procedural TEE and angiography, and the actual device size.

Introduction Atrial fibrillation (AF), the most common cardiac arrhythmia, poses challenges in predicting thromboembolic risk. While the CHADS-VASc (congestive heart failure, hypertension, age ≥ 75 years (doubled), type 2 diabetes mellitus, previous stroke, transient ischemic attack, or thromboembolism (doubled), vascular disease, age 65-74 years, and sex category) score remains essential, its limitations include failure to identify left atrial (LA) thrombus in some patients. Transesophageal echocardiography (TEE) provides superior detection of LA thrombi and thrombogenic factors compared to transthoracic echocardiography (TTE), improving risk stratification, especially in intermediate-risk groups.
