11/2782. 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. ( info)

12/2782. 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. ( info)

13/2782. 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. ( info)

14/2782. 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. ( info)

15/2782. Subdivided left atrium mimicking a cardiac tumor.

    We describe a 25-year-old man with a subdivided left atrium. The lesion was misdiagnosed preoperatively as a cardiac tumor because echocardiographic and magnetic resonance imaging revealed a solid mass arising from the posterior wall of the left atrium. Cardiac surgery revealed a small accessory chamber draining the two left pulmonary veins. No membranous structure was evident between the chamber and the left atrium. The solid mass identified noninvasively was a hypertrophic muscle which formed a wall of the accessory chamber. ( info)

16/2782. 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. ( info)

17/2782. Surgical resection of intracardiac gastrinoma.

    There has been only one previous report of an intracardiac gastrinoma causing zollinger-ellison syndrome. In this communication we describe the successful surgical resection of a gastrinoma located in the interventricular septum using cardiopulmonary bypass, blood cardioplegia, and mild hypothermia. Preoperative evaluation and histologic examination of the resected tumor strongly suggest that this was a primary intracardiac gastrinoma. ( info)

18/2782. Cardiac pheochromocytoma: resection after diagnosis by 111-indium octreotide scan.

    Cardiac pheochromocytoma is an exceedingly rare and unusual clinical entity. Only 37 previous surgically treated adult patients were found in review of the surgical literature. We report the case of a 13-year-old boy who had a cardiac pheochromocytoma that was localized by the 111-indium diethylenetriamine pentaacetic acid octreotide scintigraphy scan and confirmed by magnetic resonance imaging after computed tomographic and B1-iodine-metaiodobenzylguanidine scans had failed. At operation, a 6-cm pheochromocytoma of the left atrium was found and successfully resected with reconstruction of the left atrium using autologous pericardium. ( info)

19/2782. 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. ( info)

20/2782. Sudden death after a cold drink: case report.

    We report a case of sudden cardiac death in a 12-year-old boy after rapid ingestion of a frozen slurry drink. The cause of death was determined to be a cardiac arrhythmia secondary to a previously undiagnosed cardiac rhabdomyoma with associated myocardial scarring. Ingestion of cold liquids has been associated with syncope, but not sudden cardiac death. In this case, bradycardia induced by cold-induced vasovagal reflex may have precipitated the terminal arrhythmia. Ingestion of cold liquids should be considered a potential trigger for fatal cardiac arrhythmias in patients with underlying heart disease. ( info)
