The echocardiographic findings by transesophageal and transthoracic techniques were compared in 16 patients with right atrial mass lesions diagnosed by transesophageal echocardiography. In only 8 of the 16 patients were the masses imaged by transthoracic echocardiography. Masses in the main body of the right atrium (three of five), as well as those associated with indwelling catheters and pacer...

OBJECTIVES Our aim was to determine the diagnostic value of transesophageal echocardiography in right-sided endocarditis. BACKGROUND Recent studies have demonstrated that transesophageal echocardiography is superior to transthoracic echocardiography in the detection of vegetations associated with left-sided endocarditis. Its diagnostic value in right-sided endocarditis has not been establishe...

AIMS There existed an ambiguity in the current echo literature about the identification of the pulmonary veins imaged by echocardiography. This study was designed to identify the site and blood flow of individual pulmonary veins by transthoracic echocardiography. METHODS AND RESULTS Transthoracic echocardiography was used to display individual pulmonary veins in the apical and parasternal sho...

BACKGROUND AND PURPOSE Our case report deals with the importance of detailed echocardiographic examination for differential diagnosis of coronary sinus dilation and development of abnormalities of great thoracic veins. CASE PRESENTATION A 49-year-old man underwent transthoracic echocardiography for atypical chest pain. A dilated coronary sinus was found and venous contrast echocardiography ra...

nique (Table I). The differences of 2 mm Hg and 1 mm Hg in peak and mean gradients, respectively, were not considered to be of clinical significance. Subsequent cardiac catheterization performed 48 hours later confirmed a mean mitral prosthetic diastolic gradient of 13 mm Hg. The calculated mitral valve area was 0.7 cm2. The excised mitral valve prosthesis revealed extensively thickened and cal...

OBJECTIVE To study the incidence of spontaneous echo contrast in left atrium of Indian patients with rheumatic mitral stenosis in normal sinus rhythm and to define its relations. SUBJECTS Transthoracic and multiplane transoesophageal echocardiographic studies were performed in 89 consecutive patients with rheumatic mitral stenosis who were in normal sinus rhythm. RESULTS Spontaneous echo co...

We describe the case of a 57-year-old man with severe refractory hypoxemia, despite receiving ventilation therapy with 100% oxygen, following a gunshot wound to his left chest. A limited CT scan of the chest with contrast raised the suspicion of an arteriovenous (AV) fistula. Contrast-enhanced transthoracic echocardiography confirmed the presence of a pulmonary AV fistula. Traumatic pulmonary A...

introduction the eustachian valve (ev) remnant, when present in adults, is usually rudimentary. however, in echocardiographic examinations, it may appear as a mobile long structure in the right atrium, and it rarely protrudes into the right ventricle. when it is quite large, the ev remnant could be misdiagnosed as a right atrial tumor, thrombus, or vegetation. case presentation an 83-year-old p...
