Real‐Time Three‐Dimensional Stress Echocardiography

Cardiovascular stress testing plays a crucial role in the initial detection of coronary artery disease. In exercise stress echocardiography, the rapid acquisition of echocardiographic images is critical for accuracy. Real-time three-dimensional echocardiography permits the rapid acquisition of a volumetric data set that includes the entire left ventricle and allows the review of multiple, standard two-dimensional images from a single volumetric data set. Volumetric data can be obtained using both apical and parasternal windows. Often, satisfactory images are obtained in the majority of both prestress and poststress imaging using only an apical volume set. The following is a review of the current applications of real-time three-dimensional echocardiography in stress testing.
