Figure 3 Example of the Effect of Contrast Agent Use on DSE in a Patient With Suboptimal Endocardial Visualization
Quad-screens of end-systolic frames from the 4-chamber view of noncontrast dobutamine stress echocardiographic images (left) (Online Video 1) and contrast-enhanced images (right) (Online Video 2) are shown. Noncontrast images had significant endocardial dropout and identified an apical fixed wall motion abnormality. Contrast agent enhancement clearly delineated the endocardial segments and allowed the identification of ischemia in the lateral wall and apex (arrows) as well as dilation of the ventricle at end-systole at maximal stress. DSE = dobutamine stress echocardiography.
