1/2782. 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. ( info)

2/2782. syncope two years after hysterectomy.

    A 61-year-old woman presented to the emergency department after experiencing palpitations, shortness of breath, and syncope while taking a shower. Her husband revived her with mouth-to-mouth resuscitation. She had had a similar episode three days earlier while making her bed and had lost consciousness for about 10 sec. She did not appear to have had a seizure. Five months earlier, while taking a walk, she had experienced dizziness, dyspnea, and chest pressure lasting about an hour. A workup at that time included cardiac catheterization, lung scanning, and esophagogastroduodenoscopy, but no abnormality was found. lower extremity edema was noted. ( info)

3/2782. Unusual cause of intraoperative hypotension diagnosed with transoesophageal echocardiography in a patient with renal cell carcinoma.

    Transoesophageal echocardiography (TOE) is not commonly used in the management of non-cardiac cases. We report a case where the use of TOE played a major role in the intraoperative diagnosis and subsequent management of a patient exhibiting severe hypotension whilst undergoing a nephrectomy. The rare diagnosis of a secondary intraventricular tumour would not have been evident with more conventional monitoring techniques. ( info)

4/2782. 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. ( info)

5/2782. Detection of cardiac myxoma by F-18 FDG PET.

    Intracardiac tumors occur infrequently and are difficult to diagnose with CT and MRI. The authors describe the successful imaging of a right atrial myxoma with F-18 FDG PET. ( info)

6/2782. Primary pericardial mesothelioma with cardiac tamponade and distant metastasis: case report.

    Although cardiac tamponade is a well-known complication of malignancy, it is uncommon as the initial manifestation. The antemortem diagnosis is difficult and distant metastasis is extremely rare. The presentations of primary pericardial mesothelioma are nonspecific. Pathologically, mesothelioma is the most common in primary tumors of the pericardium. Radical surgery can be used to treat a localized mesothelioma. However, the therapy for advanced primary pericardial mesothelioma is usually palliative because it is resistant to irradiation, and chemotherapy does not markedly improve the outcome. The prognosis is uniformly poor. The median survival from the onset of symptoms is 6 months. We present a 67-year-old woman with cardiac tamponade 4 months prior to a definitive diagnosis of primary pericardial mesothelioma. A computed tomogram confirmed multiple well-enhanced nodules in the pericardium, lungs and liver. Unfortunately, the patient died of multiple organ failure. ( info)

7/2782. 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. ( info)

8/2782. Coil embolization of coronary supply to a cardiac metastasis.

    Coil embolization of tumor-related coronary arteries was successful in interrupting coronary supply to a cardiac metastasis from uterine leiomyosarcoma. In patients with cardiac metastases of highly malignant tumors this may be a palliative therapeutic approach. ( info)

9/2782. 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. ( info)

10/2782. 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. ( info)
