11/202. Clinically significant cardiac infiltration in acute leukemia, lymphocytic lymphoma, and plasma cell myeloma.Cardiac infiltration by hematologic neoplasms leading to clinically significant cardiovascular disease is rare. Three such cases are described in this report, and it is suggested that rare manifestations of hematologic neoplasms may become more common in the future since these diseases are more amenable to therapy than heretofore. Cardiac involvement with hematologic neoplasms is of more than academic interest since this complication is likely to respond to radiotherapy.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
12/202. A large false aneurysm of the right ventricle within a giant epicardial lipoma.Lipomas, which account for approximately 10% of all neoplasms of the heart, may be detected in asymptomatic patients by chance during echocardiography, CT scan, or MRI scan. Occasionally, lipomas are complicated by arrhythmias. We describe a patient who presented with severe cardiomegaly and paroxysmal supraventricular tachycardia. An MRI scan showed a large intrapericardial lipoma with two large cavities inside communicating with each other and with the right ventricular chamber through a defect of the right ventricular wall. The mass was partially removed, and the right ventricle was patched. Surgery combined with antiarrhythmic therapy resulted in a good short-term result.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
13/202. A left atrial paraganglioma patient presenting with compressive dysphagia.Paragangliomas are rare neoplasms of neural crest origin arising in the chromaffin (pheochromocytoma) and chemoreceptor (chemodectoma) tissues. Only a few cases of paragangliomas have been reported in the heart. Most of the cardiac paragangliomas are located in, or adjacent to, the left atrium. The biological activity indicative of catecholamine production has rarely been shown in cardiac paragangliomas. patients with cardiac paragangliomas may present with hypertension, or with various obstructive or compressive symptoms, depending on the location of the tumour. A left atrial paraganglioma compressing the esophagus causing dysphagia is presented. A 37-year-old female patient underwent work-up for dysphagia to solids. Transesophageal echocardiography showed the presence of a large mass in the dilated left atrium. The tumour was removed completely intact and was a benign noncatecholamine-secreting paraganglioma. The patient's dysphagia was relieved. The clinical perspectives of cardiac paraganglioma and cardiac dysphagia are discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
14/202. Tumors of the cardiac valves: imaging findings in magnetic resonance imaging, electron beam computed tomography, and echocardiography.We describe the findings from various cross-sectional imaging modalities in patients with cardiac valve adherent masses. The techniques are discussed, and imaging findings are compared with the results of cardiac surgery. All three patients had neurological symptoms and/or cardiac murmurs. Transthoracic and/or transesophageal echocardiography revealed the cardiac mass in all three. For differentiation of thrombus and cardiac neoplasm magnetic resonance imaging (MRI) was also performed in all three patients and electron-beam computed tomography (EBCT) in two. Fast segmented cine gradient-echo MRI techniques provided mass depiction in all patients, while T1-weighted spin-echo imaging failed in mass detection in one patient. None of the patients showed evidence of valve regurgitation or stenosis in flow sensitive cine MRI. EBCT excluded mass calcifications in both patients and reliably demonstrated the valve attached lesions. Although echocardiography is the modality of choice in evaluating cardiac masses and especially valve attached masses, MRI and EBCT provide additional information about tissue characteristics and allows an excellent overview of the cardiac and paracardiac morphology. Fast segmented cine gradient-echo MRI is especially able to depict even small tumors attached to rapidly moving cardiac valves, and valve competence can be easily assessed within the same examination.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
15/202. Metastatic pancreatic adenocarcinoma to the heart diagnosed antemortem.Pancreatic tumors frequently metastasize widely, though it is rare to diagnose pancreatic cardiac metastases in the antemortem state. We report an unusual case of metastatic pancreatic adenocarcinoma to the right atrium. Transesophageal echocardiography showed that the tumor was attached to the superior aspect of the right atrium, prolapsing through and obstructing the tricuspid valve in diastole and retracting back into the right atrium during systole. The tumor was excised, and histologic examination confirmed the presence of moderately differentiated adenocarcinoma with a papillary architectural pattern and with desmoplastic stroma, features comparable to the original primary pancreatic neoplasm.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
16/202. Tamponade as the clinical onset of a cardiac angiosarcoma.Primary tumors of the heart are usually benign, with the malignant forms being rare. In this article we report the case of an angiosarcoma with the only manifestation being a cardiac tamponade. When the patient being admitted to the hospital, an important differential diagnosis was pulmonary tumor. A mass in the right atrium was later detected in the echocardiogram. Further image studies, such as MRI, showed spectacular images of this mass suggestive of neoplasm. An intra-operatory biopsy diagnosed the mass as an angiosarcoma. Since there was no evidence of primary neoplasm in other studies carried out, the neoformation was diagnosed as a primary angiosarcoma. Surgery was carried out with a survival of only 13 months after the procedure. We also use this case to make a brief review of the primary tumors of the heart, especially angiosarcomas.- - - - - - - - - - ranking = 0.66666666666667keywords = neoplasm (Clic here for more details about this article) |
17/202. Primary cardiac lymphoma diagnosed by percutaneous intracardiac biopsy with combined fluoroscopic and transesophageal echocardiographic imaging.Primary cardiac tumors have very low prevalence with cardiac lymphoma, being one of the rarest forms. Several recent reports have shown transesophageal echocardiography to be an accurate technique for characterizing and localizing these neoplasms, with results comparable to CT and MRI scans. Transvenous intracardiac tumor biopsy has been employed as a minimally invasive technique to obtain tissue samples. The addition of transesophageal echocardiographic (TEE) guidance to this process has increased the accuracy of obtaining diagnostic specimens while improving patient safety. We review published cases of this relatively new technique using combined fluoroscopic and TEE guidance and present a case of primary cardiac lymphoma diagnosed by this method. The patient achieved complete tumor remission after treatment with standard chemotherapy and remains fully functional 32 months after initial diagnosis.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
18/202. Intravenous leiomyomatosis extending into the right ventricular cavity: one-stage radical operation using cardiopulmonary bypass--a case report.The authors describe a 47-year-old woman with intravenous leiomyomatosis (IVL) extending into the right ventricular cavity. This rare entity is a neoplasm originating from smooth muscle of the uterus, with vermiform extensions into the inferior vena cava. The patient underwent a one-stage operation under simultaneous sternotomy and laparotomy, and radical excision of the tumor was successfully achieved with use of normothermic cardiopulmonary bypass. Although this tumor is histologically benign, it sometimes extends into the cardiac cavity and causes sudden death due to incarceration into the atrioventricular orifice. Moreover, recurrence or lung metastasis of IVL has been reported. The authors recommend a one stage-radical resection of the tumor or a two-staged operation within a short interval. In the literature, 24 surgical cases of the intravenous leiomyomatosis with intracardiac extension have been reported. The diagnosis and surgical treatment of this tumor are reviewed and discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
19/202. tricuspid valve metastasis from testicular carcinoma: a case report and review of the literature.A 20-year-old man with Stage II nonseminomatous germ cell tumor underwent chemotherapy and multiple surgical resections of recurrent abdominal and supradiaphragmatic mature teratomas. Evaluation of a new heart murmur led to the diagnosis of tricuspid valve teratoma, which required complete valve excision and replacement. We present our experience with the first discrete tricuspid valve metastasis from testicular carcinoma and review the literature regarding cardiac metastases from germ cell neoplasms.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
20/202. Primary cardiac rhabdomyosarcoma of the left atrium: an unusual presentation.rhabdomyosarcoma accounts for almost 20% of all primary malignant neoplasms of the heart. These tumors usually arise from the ventricular walls. In adult patients, they sometimes arise from the atrial walls and mimic atrioventricular valve stenosis. We describe a case of left atrial rhabdomyosarcoma that presented as severe mitral stenosis and required emergency surgery. The atrial mass was detected by transthoracic and transesophageal echocardiography, but only histopathology confirmed the nature of the lesion. Although rhabdomyosarcomas of the heart are highly lethal, operation is indicated for emergency cases, in order to clarify the diagnosis, relieve symptoms, and improve short-term survival.- - - - - - - - - - ranking = 0.33333333333333keywords = neoplasm (Clic here for more details about this article) |
