Figure 1 Echocardiographic images from the apical four-chamber and three-chamber views, at rest, intermediate stage (Intm), and peak stage of dobutamine stress in a patient with left anterior descending (LAD) and left circumflex (LCx) coronary artery disease (CAD). Perfusion abnormalities were evident in the lateral, posterior, and apical segments at intermediate phase with extension of these abnormalities at peak stress (arrows). The patient had inducible wall motion abnormalities confined to the apex at peak stress.
