Detection of left atrial appendage thrombus by cardiac computed tomography: a word of caution.

Detection of Left Atrial Appendage Thrombus by Cardiac Computed Tomography in Patients With Atrial Fibrillation: A Meta-Analysis Romero et al: Computed Tomography Assessing LA/LAA Thrombus

Severe Complications of Left Atrial Appendage Thrombi: a case report

Clinical significance of the left atrial appendage (LAA) is well-known for a cardiologist, but it's not so familiar to a radiologist. Patients with frequent dysrhythmia, especially with atrial fibrillation, often result in thrombus formation and subsequent cardioembolic events. This might be able to contribute to strokes, peripheral arteries occlusive disease (PAOD), or even death. We present a...

Diagnosis of noninfective cardiac mass lesions by two-dimensional echocardiography. Comparison of the transthoracic and transesophageal approaches.

This study was conducted in 46 patients with cardiac thrombi, 15 patients with atrial myxomas, and 32 patients with other cardiac or paracardiac tumors. Diagnoses were subsequently proven by surgery, autopsy, computed tomography, magnetic resonance imaging, or angiography in all patients. All patients underwent precordial and transesophageal two-dimensional echocardiography to assess the variou...

Thrombus in the left atrial appendage in stroke patients: detection with cardiac CT angiography--a preliminary report.

PURPOSE To assess the diagnostic performance of 64-section cardiac computed tomographic (CT) angiography for detection of left atrial appendage (LAA) thrombi in stroke patients by using transesophageal echocardiography (TEE) as the reference standard. MATERIALS AND METHODS This study was approved by the institutional review board. Records were reviewed from 101 consecutive patients who had ex...

Computed tomography for detecting left atrial thrombus: a meta-analysis

INTRODUCTION Thromboembolism, usually originating from the left atrium (LA) and left atrial appendage (LAA), is a major complication of atrial fibrillation and may result in transient ischemic attack and stroke. Computed tomography (CT) is a noninvasive test for detection of LA and LAA thrombus. We sought to conduct a meta-analysis to evaluate the accuracy of CT in detecting LA/LAA thrombus. ...
