title: [Early left ventricular dysfunction in acute myocardial infarct. Evaluation using imaging methods].
abstract: A patient admitted in a Coronary Care Unit with an acute anterior myocardial infarction, is presented. He had initially normal left ventricular function and, on the 11th day he had, suddenly, an acute pulmonary edema. The reason for this episode was detected through imaging techniques--echocardiography and isotopic studies, and consisted on infarct expansion with early evolution for apical aneurysm. Contrast angiography confirmed the presence of a huge aneurysm and two vessels disease. Tallium Scintigraphy showed reversible ischemia beyond necrotic areas. The patient was submitted to aneurysmectomy and received three aorto-coronary bypass. He is now doing well, in class I, NYHA. The discussion emphasizes the actual role of imaging techniques in the diagnosis of infarct expansion and early functional aneurysm. We discuss the prognostic of infarct expansion and the importance of perfusion studies on defining areas of myocardium in jeopardy, enabling a better surgical approach.
