Right Atrial Mass (right + atrial_mass)
Selected AbstractsAcinetobacter Endocarditis Presenting as a Large Right Atrial Mass: An Atypical PresentationECHOCARDIOGRAPHY, Issue 4 2010Sherrita Bhagan-Bruno M.D. This paper discusses a 26-year-old woman with end-stage renal disease on hemodialysis and Acinetobacter calcoaceticus-baumannii complex endocarditis. The patient had an indwelling right internal jugular catheter that was probably the nidus of infection. Transthoracic echocardiogram revealed an atypical presentation of the endocarditis as a large intracardiac mass, measuring in centimeters and occupying more than 50% of the right atrial cavity. The mass was attached to the lateral wall of the right atrium without valvular involvement. The patient was treated with prompt removal of the indwelling catheter, intravenous antibiotics, and surgical resection of the mass with an uneventful recovery. A literature search for cases of "Acinetobacter endocarditis" reveals this as the first case reported of Acinetobacter endocarditis presenting in this manner. (Echocardiography 2010;27:E39-E42) [source] A Large Saphenous Vein Graft Aneurysm Presenting as a Right Atrial Mass: A Case ReportECHOCARDIOGRAPHY, Issue 6 2006Shemy Carasso M.D. An aneurysm of a saphenous vein graft (SVG) is a rare but potentially fatal complication of coronary artery bypass grafting (CABG). We describe a case of a large SVG aneurysm (7 × 6 cm) compressing the right atrium. The patient presented with chest pain, dyspnea and desaturation, and a right intra-atrial mass was revealed on echocardiography. The differential diagnosis of intracardiac masses revealed by echocardiography should include extrinsic lesions. Due to its potential lethal complications, an SVG aneurysm should be considered in a post-CABG patient presenting with acute coronary syndrome or heart failure.

Cardiac magnetic resonance angiography reliably made a diagnosis of SVG aneurysm extrinsically compressing right atrium. This case illustrates the importance of using combined imaging modalities for the diagnosis and management of cardiac masses. [source] Eleven-Year Experience in Diagnosis and Surgical Therapy of Right Atrial MassesJOURNAL OF CARDIAC SURGERY, Issue 1 2007Nezihi 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.

[source] Lipoma of the right atriumJOURNAL OF CLINICAL ULTRASOUND, Issue 3 2009Oyku Gulmez MD Abstract A 66-year-old asymptomatic woman was admitted to our hospital with the diagnosis of a right atrial mass detected on an outside transthoracic echocardiogram and confirmed on transesophageal echocardiography. Physical examination and basal electrocardiogram were normal. Transthoracic echocardiography revealed a 3.8 × 2.5 cm echogenic mass in the right atrium. A multislice CT examination demonstrated a right atrial mass with a fat density ranging from ,80 to ,110 HU. The patient had a successful surgical excision of the mass, and the diagnosis of lipoma was confirmed on histopathological examination. © 2008 Wiley Periodicals, Inc.

Leissner M.D. Methods: Bivalirudin was used during CPB and deep hypothermic circulatory arrest (DHCA) for resection of multiple right atrial masses in a patient with HIT II and antiphospholipid antibodies syndrome (APS). Anticoagulation was monitored with the activated clotting time (ACT) and a target ACT of 450 seconds or greater was maintained. Results: Surgical removal of multiple right atrial masses was successful and there was no evidence of thromboembolic events. Clot was noticed in the cardiotomy and venous reservoir after CPB was discontinued and the system flushed. The postoperative course was uneventful. Conclusions: Anticoagulation was successfully managed with bivalirudin, a new short-acting, and direct thrombin inhibitor. Further studies are necessary to evaluate the safety of bivalirudin during DHCA. [source] | ||||||||||
