Abstract
The introduction of real-time three-dimensional (RT-3D) echocardiography during dobutamine-induced stress was a major leap forward in our diagnostic armamentarium for the evaluation of ischemia. 1 Ahmad M. Xie T. McCulloch M. Abreo G. Runge M. Real-time three-dimensional dobutamine stress echocardiography in assessment stress echocardiography in assessment of ischemia: comparison with two-dimensional dobutamine stress echocardiography. J Am Coll Cardiol. 2001; 37: 1303-1309 Abstract Full Text Full Text PDF PubMed Scopus (133) Google Scholar Although two-dimensional (2D) stress echocardiography provides excellent diagnostic and prognostic information, it has a number of technical limitations, including the time required to perform the procedure and operator-dependent image acquisitions. Using 2D echocardiography, it is difficult to precisely match myocardial segments between baseline and stress. RT-3D echocardiography for the first time provided rapid acquisition at peak stress, with a more precise comparison of myocardial segments between baseline and stress. The ability to obtain all images in 1 heartbeat was exciting and opened a whole new approach to the analysis of stress images.
