Clinical and Echocardiographic Risk Factors for Embolization in the Presence of Left Atrial Thrombus

ECHOCARDIOGRAPHY, Issue 5 2007

Aims: The aim of our study was to evaluate the factors leading to embolization in patients with left atrial thrombi (LAT). With this purpose, we retrospectively analyzed clinical, transthoracic, transesophageal echocardiographic data of patients with LAT in the transesophageal echocardiographic evaluation. Methods and Results: One hundred ninety-two patients with LAT not on anticoagulant therapy were divided into two groups according to the presence of prior ischemic stroke. The group with ischemic stroke included more patients with sinus rhythm and less patients with mitral stenosis. They had smaller left atrial diameter, more left atrial appendage spontaneous echo-contrast, higher appendage ejection fraction, and emptying velocity. Conclusion: Once the thrombus has been formed, cerebral embolization seems to be higher in patients with relatively preserved appendage ejection fraction and emptying velocity. Presence of atrial appendage spontaneous echo-contrast also favor embolization. Factors leading to embolization seem to differ in some respects from the causes of thrombus formation. [source]

Implantation of Bilateral Carotid Artery Filters to Allow Safe Removal of Left Atrial Thrombus During Ablation of Atrial Fibrillation

Left atrial clot formation is a feared complication of catheter ablation for atrial fibrillation. We report a case of left atrial thrombus that formed around the circular mapping catheter before the delivery of RF. Successful retrieval of the clot was obtained by withdrawing the catheters while protecting the anterior cerebral circulation by positioning temporary carotid artery filters. [source]

Assessment of the Vascularity of a Left Atrial Mass Using Myocardial Perfusion Contrast Echocardiography

Sahar S. Abdelmoneim M.D. M.Sc.
Emerging applications of myocardial contrast echocardiography (MCE) include the evaluation of myocardial perfusion, the improvement of the definition of intracavitary structures, and evaluation of the relative perfusion of a cardiac mass. We present a case of a patient that was found incidentally to have a cardiac mass on transthoracic echocardiography. MCE was used to evaluate the vascularity of the mass. This case is compared with another patient with a left atrial thrombus, which represents an "avascular" cardiac mass by MCE. [source]

Magnetic resonance imaging of acute myocardial infarction in dextrocardia with situs solitus (dextroversion)

Summary The case report of an 88-year-old woman with dextroversion and acute anterior wall myocardial infarction is presented. The patient, who had been diagnosed with dextrocardia 3 years prior to this admission, presented with right-sided chest pain. Coronary angiography demonstrated an 80% proximal left anterior descending artery stenosis which was successfully stented. A cardiac MRI was performed to exclude a left atrial thrombus after an inconclusive echocardiogram. The MRI demonstrated findings consistent with dextroversion, with delayed contrast-enhanced viability sequences confirming a near transmural anterior wall myocardial infarct. To our knowledge, this is the first report illustrating the cardiac MRI findings in such a case. [source]
