1/1329. Intracardiac leiomyomatosis: echocardiographic features.Intravenous leiomyomatosis is a histologically benign smooth-muscle tumor arising from either a uterine myoma or the walls of a uterine vessel with extension into veins. Echocardiographic features of two cases of intravenous leiomyomatosis with extensive spread into the right-sided cardiac chambers and pulmonary arteries are described. Both patients were middle-aged women, with prior history of hysterectomy 12 and 10 years earlier who presented with cardiac symptoms and signs. Distinctive echocardiographic features include 1) elongated mobile masses extending from the veins of the lower body, including inferior vena cava and azygos vein; 2) multiple venous attachments or metastases; and 3) filling of venous vessels and right-heart chambers. Intracardiac leiomyomatosis should be considered in a female patient presenting with an extensive mass in the right-sided cardiac chambers.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
2/1329. Intra-atrial myxomas, clinical-pathologic correlation based on two case studies including historical review.The two cases of left-sided myxomas are reported with both patients having had uneventful cardiac surgery. One patient had an uneventful recovery and is doing well, whereas the second patient (female) had a complicating cerebrovascular accident. This patient was thought to have myxoma embolization; however, histopathologic verification could not be obtained. This latter patient had of course a higher risk of developing thromboembolization, due to the concomitant valve surgery procedure. The clinical, operative and pathologic studies confirm the lesions as primary myxomas and support and amplify the diagnostic concept of those lesions being of neoplastic nature, and countermand the previously commonly held concept of the thrombotic nature of myxomas. The nature of the myxoma is the primitive mesenchymal vasoformative cells of the atrial subendocardium, which is equivalent to the subendocardial cushion cell.- - - - - - - - - - ranking = 0.13595847032283keywords = valve (Clic here for more details about this article) |
3/1329. mitral valve repair for anterior leaflet papillary fibroelastoma: two case descriptions and a literature review.Cardiac papillary fibroelastomas are rare cardiac tumors and have been considered a 'benign' incidental finding that may have significant clinical manifestations. In this paper we report two cases of mitral valve fibroelastoma: one was discovered by chance with transthoracic echocardiography in a young healthy man, the other was an intraoperative incidental finding in a middle aged man with a recent history of acute myocardial infarction. The mitral valve was repaired in both cases after excising the tumor. The patients did well and remain asymptomatic. A literature review was compiled which comprises previous case reports of 34 patients with mitral valve papillary fibroelastomas. Most were asymptomatic, but when symptoms occurred, they could be disabling, such as stroke, cardiac heart failure, myocardial infarction, and sudden death. Papillary fibroelastoma is amenable to simple surgical excision or in addition to mitral valve repair or replacement. recurrence has not been reported.- - - - - - - - - - ranking = 2.0876677625827keywords = heart, valve (Clic here for more details about this article) |
4/1329. Intrapericardial yolk sac tumor associated with acute myocarditis.An occult intrapericardial yolk sac tumor occurred in a 3-year-old girl with a fatal outcome. At autopsy, a 5.5-cm mass surrounded the base of the heart and compressed the left atrium posteriorly. Histologically, the tumor was a pure yolk sac tumor. Postmortem chemical analyses of the blood revealed an alpha-fetoprotein level greater than 7000 microg/L. Acute myocarditis of both ventricles was also found.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
5/1329. Echocardiographic diagnosis of large fungal verruca attached to mitral valve.In a patient with endocarditis due to candida tropicalis echocardiograms from mitral valve vegetations were found to mimic the typical pattern of a left atrial myxoma. A mass was shown occupying the mitral orifice posterior to the anterior mitral leaflet; densities also appeared in the left atrium.Though these echocardiographic findings were consistent with the diagnosis of a left atrial myxoma, there were other distinctive differential diagnostic features. Other diagnostic possibilities must, therefore, be considered in the interpretation of echocardiograms which suggest left atrial tumour.- - - - - - - - - - ranking = 0.67979235161417keywords = valve (Clic here for more details about this article) |
6/1329. Neoplastic thrombotic endocarditis of the tricuspid valve in a patient with carcinoma of the thyroid. Report of a case.A rare case of neoplastic thrombotic endocarditis of the tricuspid valve in a patient with poorly differentiated follicular carcinoma of the thyroid is described. Although some previous reports documented extension of the follicular thyroid carcinoma into the great veins of the neck to the right cardiac chambers, this seems to be the first report of a neoplastic thrombotic lesion of the tricuspid valve in a patient with thyroid carcinoma. In our institute, where about 2,500 autopsies are performed yearly, and about 600 valvular lesions are discovered, such a lesion was never detected. In patients with carcinoma, a neoplastic thrombotic endocarditis may be a source of microembolic neoplastic spread leading to a possible pulmonary colonisation.- - - - - - - - - - ranking = 0.815750821937keywords = valve (Clic here for more details about this article) |
7/1329. Primary pericardial synovial sarcoma: a case report and literature review.Primary synovial sarcoma of the heart is a rare tumor, with only six previous cases having been reported in the literature. Treatment has included surgery with or without chemotherapy. We present the first case of a documented synovial sarcoma arising from the pericardium in a 19-year-old man. Molecular analysis for t(X; 18) SYT-SSX gene fusion was positive. radiation treatment was given postoperatively to the entire heart with a boost to the area where the margins were positive.- - - - - - - - - - ranking = 2keywords = heart (Clic here for more details about this article) |
8/1329. Symptomatic mitral myxomatous transformation in the elderly.The clinical and pathological features of four patients with intractable heart failure, due to myxomatous change in the mitral valve, are described. It is suggested that this change may represent a response of ageing connective tissue to mechanical stress.- - - - - - - - - - ranking = 1.1359584703228keywords = heart, valve (Clic here for more details about this article) |
9/1329. Squamous cell metastasis from the tongue to the myocardium presenting as pericardial effusion.Cardiac metastasis from head and neck cancer is rarely encountered. We present a base-of-tongue squamous cell carcinoma with metastasis to the heart that was diagnosed antemortem. autopsy series indicate that tongue cancer may metastasize more frequently to the heart than from other head and neck sites. However, none of these studies was controlled. Most importantly, cardiac metastasis should be suspected in any patient with cancer in whom new cardiac symptoms develop. The diagnosis is best confirmed with two-dimensional echocardiography or cardiac MRI. A myocardial or endocardial biopsy specimen can be obtained with angiographic guidance. Despite the improvement in diagnostic capability, available treatments are only palliative. All patients eventually die of their metastatic disease.- - - - - - - - - - ranking = 2keywords = heart (Clic here for more details about this article) |
10/1329. Acute myocardial infarction: a rare presentation of pancreatic carcinoma.Secondary neoplastic involvement of the heart is common but usually asymptomatic. Malignancy rarely presents as acute pericarditis, cardiac tamponade, and myocardial infarction in the same patient. We report a patient with unsuspected metastatic pancreatic adenocarcinoma who presented with acute pericarditis and cardiac tamponade and subsequently developed a myocardial infarction due to coronary artery occlusion secondary to a metastatic deposit around the left anterior descending artery.- - - - - - - - - - ranking = 1keywords = heart (Clic here for more details about this article) |
