A case of asymptomatic right atrial cavernous hemangioma in a 50-year-old man is reported. With right atriotomy under total cardiopulmonary bypass, the right atrial mass was identified as arising from the noncoronary Sinus of Valsalva. The mass was successfully resected with the Sinus of Valsalva closed primarily. The patient is alive and well 9 months(More)
Double-phase planar scintigraphy using 99mTc-MIBI has been introduced as a means to detect and localize parathyroid adenomas. Focal uptake on both early and delayed imaging is typical of these entities. We report a patient with persistent hypercalcemia following subtotal parathyroidectomy, who was found scintigraphically to have an ectopic parathyroid(More)
BACKGROUND The diagnosis of viable myocardium in the setting of ischemic left ventricular systolic dysfunction might indicate which patients have the greatest prognostic benefit from myocardial revascularization. Single-photon emission CT (SPECT) thallium-201 (201Tl) scintigraphy for the detection of viable myocardium is widely available in the community,(More)
Enteric pathogens rarely involve organs other than those of the gastrointestinal system. We have reported the case of a woman with rheumatoid arthritis who had endogenous endophthalmitis due to Salmonella arizonae and Hafnia alvei. The infection probably resulted from the use of snake powder as a food seasoner. After appropriate intravenous, intraocular,(More)
Pulmonary thromboembolism is a potentially fatal disease characterized by a highly variable clinical presentation. Mortality rises dramatically with right atrial thromboembolism. In our case right atrial and pulmonary thromboembolism mimicked unstable angina. A high index of suspicion and early use of echocardiography can lead to the prompt diagnosis and(More)
UNLABELLED The purpose of this study was to determine the orogastric transit time of standard 131I capsules and the incidence of transit delay. METHODS We studied 58 consecutive subjects receiving outpatient diagnostic and therapeutic 131I dosages. A standard ion chamber survey meter, placed over the left upper quadrant of the abdomen, monitored(More)
A 78-year-old man underwent mitral valve replacement with a no. 33 Hancock porcine bioprosthesis for severe mitral regurgitation. Postoperatively, a transthoracic echocardiogram (TTE) revealed a mean mitral valve gradient (MVG) of 4 mm Hg, a calculated mitral valve area (MVA) of 2.8 cm(2), and no mitral regurgitation. Eighteen months later, he presented to(More)
