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

    ECHOCARDIOGRAPHY, Issue 5 2007
    Ela Sahinbas Kavlak
    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

    ECHOCARDIOGRAPHY, Issue 5 2008
    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]

    Eleven-Year Experience in Diagnosis and Surgical Therapy of Right Atrial Masses

    JOURNAL OF CARDIAC SURGERY, Issue 1 2007
    Nezihi Kucukarslan M.D.
    A review of surgical experience with right atrial tumors in 11 patients from our institution has been presented in this article. Methods: Eleven cases, operated for a tumor mass in the right atrium in our institution between January 1993 and December 2004, were retrospectively reviewed for their clinical presentation, diagnostic workup, method of surgical procedure, and histopathologic findings. Electrocardiogram, transthoracic, and transesophageal echocardiography, computerized tomography, and nuclear magnetic resonance imaging were available for all patients during the diagnostic evaluation. Surgical procedure notes, photos, and file recordings were reviewed when available. The surgeons were also interviewed when necessary. Results: Right atrial tumors were diagnosed in 11 patients (6 males and 5 females). The average age of the patients was 34 ± 11 years (ranging between 21 and 65 years). The histopathological examination of the surgically removed specimen revealed a benign tumor in eight patients (73%), and a malignant process in three (23%). In eight patients with a benign tumor, atrial myxoma was the leading cause in half of the cases. Hydatid cyst (n = 2), lipoma (n = 1), and right atrial thrombus (n = 1) were detected in the remaining four patients. One patient died of heart failure after surgery. The diameters of the excised masses were 2 ± 0.5 cm versus 7 ± 1 cm. Conclusions: Tumors of the right atrium are rarely seen, and necessitate a unique attention during the process of diagnosis and surgical treatment. We present our surgical experience of 11 patients with right atrial mass. The differentiation of the right atrial tumors with the diagnostic tools before surgery, the determination of the spreading, and the structural properties of the mass may designate surgical approach and prognosis.

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

    JOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 5 2005

    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]

    Resolution of atrial thrombosis with heparin in a newborn with atrial flutter

    ACTA PAEDIATRICA, Issue 7 2009

    Abstract Atrial thrombosis is a relatively rare event in children. We report a case of a newborn with AFI who after restoration of sinus rhythm, developed atrial thrombus on a prominent Chiari network floating between the right and left atrium through the patent foramen ovale. The thrombus was resolved following treatment with heparin without events. Conclusion:, Atrial stunning was proposed as a key mechanistic phenomenon because the thrombus occurred after the cardioversion of AFI to sinus rhythm. Heparin may be effective in the resolution of atrial thrombus within a few days. [source]

    Prolonged low-dose thrombolytic therapy: A novel adjunctive strategy in the management of an infected right atrial thrombus

    CLINICAL CARDIOLOGY, Issue 7 2002
    Sheila Chuang M.D.
    Abstract An 81-year-old man presented with a large, infected right atrial thrombus that was refractory to anticoagulants and several courses of antibiotics. The risk of surgical removal of the thrombus, which was associated with a pacemaker electrode, was considered prohibitive. The patient was treated for 7 days with low-dose (40 mg/day) tissue-type plasminogen activator (t-PA). Hemostatic monitoring during infusion revealed (1) aplasma t-PA antigen that was approximately 5% of that achieved during short-course t-PA for acute myocardial infarction, (2) biochemical evidence of prolonged clot lysis, and (3) no significant depletion of fibrinogen or plas-minogen. Nearly complete dissolution of the thrombus was observed. His bacteremia was eradicated by intravenous penicillin despite the presence of the pacemaker lead. This case highlights the benefits of combined antibiotic and thrombolytic therapy and documents for the first time the response of the human hemostatic system to prolonged t-PA infusion and the plasma t-PA levels attained when thrombolytic therapy is administered in this manner. Prolonged courses of fibrinolytic agents may be a good alternative to surgical intervention in selected patients with infected, right-sided intracardiac thrombi. [source]
