Comparative StudyAssessment of myocardial viability at dobutamine echocardiography by deformation analysis using tissue velocity and speckle-tracking.
Comparison of myocardial tissue-velocity imaging (TVI) and speckle-tracking echocardiography (STE) for prediction of viability at dobutamine echocardiography (DbE). ⋯ Combination of TVI or STE methods with DbE can predict viability, with TVI strain and SR at LDD being the most accurate. TVI measures can predict viability in both anterior and posterior circulations, but STE measurements predict viability only in the anterior circulation.

This report reviews the development and clinical application of myocardial perfusion imaging with myocardial contrast echocardiography (MCE). This includes the development of microbubble formulations that permit the detection of left ventricular contrast from venous injection and the imaging techniques that have been invented to detect the transit of these microbubbles through the microcirculation. ⋯ A review of the clinical studies that have examined the clinical utility of myocardial perfusion imaging with MCE during rest and stress echocardiography is then presented. The limitations of MCE are also discussed.
