1/59. Co-existing left atrial thrombus and myxoma in mitral stenosis--a diagnostic challenge.We report an unusual case of an adult who underwent a mitral valve replacement with concomitant excision of the left atrial myxoma and thrombus. echocardiography showed the presence of a large "thrombus" within the left atrial appendage, body and atrial septum. There was difficulty in trying to distinguish between the atrial thrombus and myxoma due to their morphological similarities. At time of surgery, frozen section confirmed the atrial septal component of the thrombus to be an atrial myxoma and the atrial septum was excised to obtain a clear margin.- - - - - - - - - - ranking = 1keywords = appendage (Clic here for more details about this article) |
2/59. Clinical and echocardiographic features of two large left atrial parietal thrombi.A 62-year-old woman with severe mitral stenosis and two large parietal thrombi inside the left atrium is described. The patient was admitted to the hospital because of heart failure. Transthoracic and transesophageal echocardiography showed a severe calcific mitral stenosis and two large (56.9 and 46.2 mm in diameter) parietal thrombi inside the left atrium attached to the interatrial septum and associated with severe spontaneous echo contrast. This severe spontaneous echo contrast was detected in the left atrium and in the left atrial appendage. The patient was referred for cardiac surgery. The two large parietal thrombi were removed, and the valve was replaced with a Sorin-Bicarbon mitral valve prosthesis. Intraoperative transesophageal echocardiography after replacement of the mitral valve prosthesis and removal of the thrombotic mass showed absence of any spontaneous echo contrast in the left atrium and in the left atrial appendage. This report describes the diagnostic approach and successful surgical treatment of two very large parietal thrombi inside the left atrium associated with severe mitral stenosis and atrial fibrillation, which is a rare occurrence.- - - - - - - - - - ranking = 2keywords = appendage (Clic here for more details about this article) |
3/59. adenocarcinoma of the stomach with tumor-thrombotic microangiopathy in an 11-year-old male patient.The majority of malignancies in childhood are represented by leukemias, lymphomas or other reticuloendothelial neoplasms, tumors of the central nervous system, nephroblastomas and sarcomas. Gastrointestinal tumors represent less than 5% of pediatric neoplasms and carcinomas within this subgroup have been very rarely described, especially those arising in the stomach. In this study, we report a case of an 11-year-old boy with a signet-ring carcinoma of the stomach. The patient initially presented with respiratory symptoms which were caused by massive pulmonary lymphangiosis carcinomatosa and a peculiar microangiopathy, recently addressed as pulmonary tumor thrombotic microangiopathy. To our knowledge, this constellation has not been reported so far.- - - - - - - - - - ranking = 0.0014165914606283keywords = neoplasm (Clic here for more details about this article) |
4/59. Transesophageal echocardiographic diagnosis of thrombus in accessory lobes of the left atrial appendage.Fifty-four percent of left atrial appendages have two lobes. The number ranges from one to four lobes. We describe three patients with accessory lobes of the left atrial appendage studied with multiplanar transesophageal echocardiography (TEE). In one patient there was evidence of thrombi in the accessory lobe.- - - - - - - - - - ranking = 6keywords = appendage (Clic here for more details about this article) |
5/59. A case of left atrial appendage thrombus with embolic stroke in association with aortic stenosis in sinus rhythm.Although left atrial appendage (LAA) thrombus formation in the presence of sinus rhythm may potentially be the source for embolic events in various types of heart disease, no cases of LAA thrombus with embolic stroke in association with aortic stenosis in sinus rhythm have been reported. We present a case of valvular aortic stenosis with cerebral embolism in a person who was in sinus rhythm and had an LAA thrombus diagnosed by transesophageal echocardiography.- - - - - - - - - - ranking = 5keywords = appendage (Clic here for more details about this article) |
6/59. Rapid formation of left atrial appendage thrombus after unsuccessful cardioversion of atrial fibrillation.The acute effect of failed attempts of cardioversion on left atrial (LA) and left atrial appendage (LAA) functions are generally considered benign and no adverse effects have been reported. We report on a subject who had rapid formation of a fresh, mobile thrombus in the LAA despite unsuccessful cardioversion and therapeutic anticoagulation.- - - - - - - - - - ranking = 5keywords = appendage (Clic here for more details about this article) |
7/59. Three-dimensional echocardiography of left atrial appendage thrombus.Transesophageal echocardiography (TEE) is superior to transthoracic echocardiography (TTE) in evaluating the left atrial appendage (LAA) as a potential cardiac source of embolus in patients with stroke. We describe two such patients in whom a TEE and subsequently a three-dimensional (3-D) reconstruction of the LAA were performed. These case reports show that 3-D echocardiography provides better visualization of LAA anatomy, and that a 3-D description of LAA morphology may be the basis of describing normal and abnormal LAA.- - - - - - - - - - ranking = 5keywords = appendage (Clic here for more details about this article) |
8/59. Renal angiomyolipoma extending into the right atrium.Renal angiomyolipomas (AMLs) are benign renal tumors that may possess the features of a malignant neoplasm, such as local and vascular invasion. We describe the diagnosis and management of a rare case of AML associated with tumor thrombus extending into the right atrium.- - - - - - - - - - ranking = 0.00070829573031415keywords = neoplasm (Clic here for more details about this article) |
9/59. Atrial thrombosis as a late complication of cardiac surgery computed tomography appearance.We present two cases of large atrial thrombi diagnosed many years after cardiac surgery. In both cases, CT showed homogeneous non-enhancing masses. In one case the mass was immediately adjacent to an area of surgical repair; neither thrombus was in the atrial appendage, a more common location for thrombosis. The combination of appropriate clinical history and CT appearance should permit recognition of delayed postoperative intracardiac thrombosis.- - - - - - - - - - ranking = 1keywords = appendage (Clic here for more details about this article) |
10/59. Thrombus in the left atrial appendage detected by intracardiac echocardiography.Radiofrequency catheter ablation (RFCA) at the ostium of the pulmonary veins can potentially cure atrial fibrillation. Left-sided ablation procedures may carry a risk of thrombo-embolic events. Emboli from intracardiac thrombus originate from the left atrial appendage (LAA) in a substantial number of patients. The presence of spontaneous echo contrast in the left atrium (LA) and LAA peak emptying flow < or = 20 cm/s are also significantly related to thrombo-embolic events. Evaluation of the anatomy of the LA and LAA prior to left-sided procedures is therefore mandatory. Intracardiac echocardiography (ice) appears an ideal technique to obtain this information during the RFCA-procedure. In the current report, we report on the use of ice detecting a thrombus in the LAA in a patient planned to undergo RFCA of pulmonary veins for atrial fibrillation.- - - - - - - - - - ranking = 5keywords = appendage (Clic here for more details about this article) |
