1/70. Left ventricular myxoma.A rare development of acute inferior myocardial infarction is reported in a 23-year-old man with no previous history of cardiovascular disease. In an echocardiographic study a left intraventricular tumour was diagnosed. Cineangiographic study showed normal coronary arteries. The tumour, a myxoma, originating in the ventricular septum, was resected through the left atrium after the anterior leaflet of the mitral valve was detached. Postoperative course was uneventful and the patient remained healthy 48 months after surgery.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
2/70. Left atrial approach to big myxoma with angiographically visible neovascularity. Report of one case.In this article, we report a 65-year-old man with a large atrial myxoma arising from the posterior wall and from the base of the right inferior pulmonary vein. The big neoplastic mass showed a large implant site. A rare atrial myxoma neovascularity arising from the atrial circumflex artery was very clearly visualized by selective coronary arteriography. The surgical approach used to resect this tumor was an isolated left atriotomy that provided excellent exposure and safe excision.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
3/70. myxoma of mitral valve associated with infective endocarditis.A 20-year-old man was hospitalized for persistent fever, embolism, and syncopal attack. echocardiography demonstrated a tumor on the mitral posterior leaflet. It was removed under extracorporeal circulation following extirpation of thrombus in the right common like artery. The tumor consisted of myxoma and vegetation with bacterial colony. myxoma and/or vegetation had destroyed the mitral posterior leaflet. Accordingly, it was necessary to perform mitral valve replacement. The postoperative course was uneventful. This is the 14th surgical case of mitral valve myxoma, and the first case of that associated with infective endocarditis.- - - - - - - - - - ranking = 0.024632609151465keywords = circulation (Clic here for more details about this article) |
4/70. Left atrial myxoma associated with acute myocardial infarction.We describe a patient with left atrial myxoma associated with acute myocardial infarction. Since hemodynamics were impaired even with the support of an intra-aortic balloon pump, the patient underwent removal of the tumor concomitant with coronary artery bypass grafting to the right coronary artery on the fifth day from infarction onset. In circumstances of life-threatening of myxoma associated with acute myocardial infarction, removal of myxoma with coronary artery bypass should be performed in an acute phase of myocardial infarction.- - - - - - - - - - ranking = 3keywords = coronary (Clic here for more details about this article) |
5/70. aortic valve myxoma.The authors report a case of aortic valve myxoma discovered in a 34-year-old patient who had suffered a transient ischemic attack. At operation, a heliocoidal gelatinous mass was found attached to the ventricular side of the right coronary cusp of the aortic valve via a pedicle. Through a ministernotomy approach the mass was excised and the cusp was repaired. Recovery was uneventful.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
6/70. Cerebral embolism from atrial myxoma in pediatric patients.We describe 2 children with cerebrovascular events caused by emboli from left atrial myxomas and review 7 other pediatric cases from the literature. Transient cutaneous eruptions involving the extremities preceded the cerebrovascular events and were most likely attributable to fragmentation of the atrial tumor with peripheral embolization. Our first case demonstrates the more common presentation with acute hemiplegia caused by cerebral infarction and the second case a transient ischemic attack manifested by more subtle features as a result of involvement of the vertebrobasilar circulation. Neither child had a history or other signs of cardiac disease. Atrial myxoma should be considered in the differential diagnosis when children present with neurologic symptoms or with signs of embolization, because surgical removal of the tumor is critical and may be curative.- - - - - - - - - - ranking = 0.024632609151465keywords = circulation (Clic here for more details about this article) |
7/70. Coronary artery aneurysms mimicking cardiac tumor.AIMS: To discuss the diagnosis of giant coronary aneurysms. methods AND RESULTS: We describe three patients in whom initial echocardiographic findings suggested cardiac tumors in the right atrium. Additional examination proved the tumor-like structures to be giant atherosclerotic coronary aneurysms of either the right coronary artery or its saphenous vein coronary bypass graft. CONCLUSION: Giant coronary aneurysms are an important differential diagnosis for cardiac tumors.- - - - - - - - - - ranking = 5keywords = coronary (Clic here for more details about this article) |
8/70. Atypical vessels as an early sign of intracardiac myxoma?We report on a woman with previously unknown left atrial myxoma, who underwent percutaneous coronary intervention. 45 months after the initial coronary angiography, echocardiography demonstrated a large atrial myxoma, which was not seen echocardiographically before. The retrospective analysis of the pre-intervention coronary angiography revealed atypical vessels in the atrial septum, which are interpreted as early signs of myxoma.- - - - - - - - - - ranking = 3keywords = coronary (Clic here for more details about this article) |
9/70. Primary cardiac tumors. diagnosis and management in 14 cases.In our experience over a 10-year period at Westchester County Medical Center (Valhalla, NY), we diagnosed 11 left atrial myxomas and three primary cardiac malignancies in ten females and four males, aged 18-74 years. Two-dimensional echocardiography enabled the correct diagnosis of these lesions. Detailed characteristics of the cardiac tumors were provided by magnetic resonance imaging (MRI) scanning in five patients. Two of three malignancies were only biopsied; the myxomas were completely excised. We emphasized removal of tumor and its attachments to the atrial wall, accomplished by left or biatrial incision, full-thickness excision of the area of attachment, and pericardial patch closure of the atrial or free-wall defects. Associated procedures included mitral valve repair (three) and coronary artery bypass grafting (two). There was no mortality associated with the surgery. Two patients with malignancy died three and 36 months after surgery; a third is alive at 30 months after surgery. No patients with myxoma has had recurrence from 16 to 100 months. Preoperative diagnosis of cardiac tumors is enhanced by MRI scanning and may help in planning the surgical procedure. Complete and timely removal of these tumors contributes to long-standing patient survival.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
10/70. Acute myocardial infarction in a 15-year old secondary to myxomatous embolisation.We present a 15-year-old white male who presented with an acute myocardial infarction secondary to embolisation of tissue from a left atrial myxoma. He successfully underwent resection of the myxoma, and embolectomy of the fragments of tumour lodged in the coronary artery.- - - - - - - - - - ranking = 1keywords = coronary (Clic here for more details about this article) |
