Figure 2 Myocardial contrast echocardiogram in a 67-year-old woman with a recent anterior wall myocardial infarction (apical four-chamber view). Two-dimensional imaging revealed akinesis of the mid- and distal left anterior descending coronary artery (LAD) territory. Despite normal antegrade flow in the LAD, there is a large perfusion defect in the akinetic zone, indicating necrosis (arrow).
