RESUMEN
We describe a patient with mitral stenosis and severely enlarged left atrium. Transthoracic echocardiography showed a false image of intraatrial thrombus, whereas transesophageal echocardiography showed massive spontaneous left atrial contrast. Intraoperative transesophageal echocardiography was performed. During cardioplegic arrest the contrast was enhanced, but it gradually and completely cleared 15 minutes after cardiopulmonary by-pass arrest. Transesophageal echocardiography is a useful technique for the study of intraatrial masses and may bring a new dimension to tissue characterization studies.

The Authors investigated the sensitivity of the ecg thoracic derivations of Condorelli in detecting non-Q myocardial infarction demonstrated by 2-D echocardiography and 201-TL scintigraphy. This technique showed a good reliability, allowing a useful diagnostic approach.

The study compared echocardiography, specially echocardiokimography, and myocardial scintigraphy in the evaluation of the extent of chronic myocardial infarction. Eighteen subjects were enrolled and the following examinations performed: ECG, M- and B-mode echocardiography, echocardiokimography and myocardial scintigraphy with Tc-MIBI, a new perfusion radionuclide agent. We concluded: 1) accordance between the two kinds of methods; 2) specificity of echocardiokimography; 3) advantage in using both methods, specially with MIBI scintigraphy.
