OBJECTIVES The purpose of this study was to determine the impact of changes in flow on aortic valve area (AVA) as measured by the Gorlin formula and transesophageal echocardiographic (TEE) planimetry. BACKGROUND The meaning of flow-related changes in AVA calculations using the Gorlin formula in patients with aortic stenosis remains controversial. It has(More)
Three patients were referred for suspicion of intracardiac tumour on transthoracic echocardiography. In all patients, the mass appeared as a nonobstructive oval structure measuring approximately 12 x 4 mm, located near the posterior third of the interatrial septum in the right atrium in the apical four-chamber view. The characteristics of the mass were not(More)
OBJECTIVES To evaluate the prevalence of thyroid dysfunction in elderly cardiac patients in an outpatient setting. SUBJECTS AND METHODS A total of 399 consecutive patients (268 women, age range 60-92 years) who were followed at Heart Institute were evaluated for thyroid dysfunction with serum free T4, TSH, anti-Peroxidase antibodies, urinary iodine(More)
Angiosarcoma of the heart is a rare tumor. This tumor is most frequently located in the right atrium and pericardium. Localization of a tumor in the interatrial septum usually suggests atrial myxoma. We report two cases of angiosarcoma originating from the interatrial septum, one extending into the right atrium and the other into the left atrium, mimicking(More)
Three patients with atopic dermatitis, one boy and two girls, aged between 6 and 17 years, presented eczematous skin, pruritus, scarifications, lichenification and a family history of atopy. During exacerbations, the patients sought emergency care and were prescribed oral corticosteroids for a period of approximately 15 days. Initially, the patients(More)
The schistosome Heterobilharzia americana infects dogs, raccoons, and other mammals in the southeastern United States. Migration of eggs into the liver results in parasitic granulomas with varying degrees of fibrosis and inflammation. Recently, hepatic parasitic granulomas in horses were shown to be caused by H. americana infection. In the present study,(More)
Mechanical prostheses induce artifacts that decrease the accuracy of conventional transthoracic echocardiographic imaging for the detection and quantitation of periprosthetic mitral regurgitation. In 15 patients undergoing transthoracic echocardiography, injection of sonicated albumin significantly enhanced the assessment of periprosthetic mitral(More)
Aneurysm of the membranous portion of the ventricular septum and accessory valvular tissue are two infrequent congenital lesions. This case illustrates a rare association of aneurysm of the membranous septum and accessory valvular tissue originating from the mitral valve, causing right-sided ventricular outflow tract obstruction in a patient with corrected(More)
A 6-year-old castrated male ferret presented with multiple black and tan proliferative skin lesions. Histologically, the lesions were characterized by multifocal plaques of irregular epidermal hyperplasia and full-thickness dysplasia, with loss of normal epithelial stratification, loss of nuclear polarity, and rare eosinophilic intranuclear inclusion bodies(More)
Small intestinal T-cell lymphoma and mucinous adenocarcinoma are rarely reported in the pig, with most lymphomas being of B-cell origin and only a single report of mucinous adenocarcinoma. Two aged Vietnamese potbellied pigs had concurrent T-cell lymphoma and mucinous adenocarcinoma of the small intestine. The lymphomas formed polypoid masses that projected(More)
