Catheter-related giant right atrial thrombosis mimicking a myxoma: A case report.

Exp Ther Med 2021 Jun 14;21(6):603. Epub 2021 Apr 14.

Department of Cardiovascular Surgery, 'Prof. Dr. C. C.' Iliescu Emergency Institute for Cardiovascular Diseases, 022322 Bucharest, Romania.

Despite the development of imagistic methods, the differential diagnosis of a right atrial mass may be difficult to be established, the most common pathologies which should be taken in consideration being represented by thrombus, tumors, prominent crista terminalis, or vegetation of infectious endocarditis. In this study, we present the case of a 63-year-old man with chronic kidney disease, in hemodialysis (HD) with a silicone central venous catheter (CVC) with the incidental transthoracic echocardiography (transthoracic echocardiogram, TTE) finding of a tumoral mass of 35x26 mm in the right atrium (RA), not related with the catheter, which was diagnosed as right atrial myxoma and underwent surgical excision. After reviewing the histopathology probe, the diagnosis of right atrial thrombus was confirmed. Read More

Fibrin-Associated, EBV-Negative Diffuse Large B-Cell Lymphoma Arising in Atrial Myxoma: Expanding the Spectrum of the Entity.

Int J Surg Pathol 2021 Apr 29:10668969211014959. Epub 2021 Apr 29.

University of Michigan, Ann Arbor, MI, USA.

Fibrin-associated diffuse large B-cell lymphoma (FA-DLBCL) is a provisional entity in the 2017 Revision of the World Health Organization Classification. This indolent entity, which is frequently discovered incidentally, is currently classified under the category of diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI), an aggressive lymphoma with poor survival. Several authors have proposed that it be classified separately since, in contrast to DLBCL-CI, transformation to aggressive lymphoma has rarely been reported and this entity has distinct clinical and histological features.

Clinical Utility and Cost of Inpatient Transthoracic Echocardiography Following Acute Ischemic Stroke.

Neurohospitalist 2021 Jan 31;11(1):12-17. Epub 2020 Jul 31.

Department of Medicine (Neurology), Ottawa Hospital Research Institute, University of Ottawa, Ottawa, Ontario, Canada.

Background And Purpose: It is unclear whether it is clinically necessary or cost-effective to routinely obtain a transthoracic echocardiogram (TTE) during inpatient admission for ischemic stroke.

Methods: We assessed consecutive patients presenting with acute ischemic stroke at a comprehensive stroke center from 2015 to 2017 who underwent TTE. We assessed for findings on TTE that would warrant urgent intervention including cardiac thrombus, atrial myxoma, mitral stenosis, valve vegetation, valve dysfunction requiring surgery, and low ejection fraction.

Department of Cardiovascular Surgery, İzmir Katip Çelebi University Atatürk Training and Research Hospital, Izmir, Turkey.

Epithelioid hemangioendothelioma is a rare malignant vascular tumor which originates from the vascular endothelial or dendritic cells and has a moderate malignancy between benign hemangioma and malignant hemangiosarcoma, arising from vascular structures. Radical resection of epithelioid hemangioendothelioma is recommended, due to both its malignant nature and the adverse effects of associated complications on mortality and morbidity. In this article, we present a rare case of primary cardiac epithelioid hemangioendothelioma accompanied by a left atrial myxoma which was treated by resection. Read More

BMJ Case Rep 2021 Mar 20;14(3). Epub 2021 Mar 20.

Department of Cardiology, ProCare Odessa Heart Institute, Medical Center Hospital, Odessa, Texas, USA.

Atrial myxoma is a benign primary heart tumour, which can be found incidentally on imaging studies. It is usually located in the left atrium and may manifest as dyspnoea, chest pain, heart failure, cough, shortness of breath when rising from a recumbent position, haemoptysis, hoarseness and as a source of cardiac embolism. However, dysphagia caused by an atrial myxoma has been reported only twice in the literature. Read More
