Assessment of myocardial viability at dobutamine echocardiography by deformation analysis using tissue velocity and speckle-tracking.


OBJECTIVES Comparison of myocardial tissue-velocity imaging (TVI) and speckle-tracking echocardiography (STE) for prediction of viability at dobutamine echocardiography (DbE). BACKGROUND Use of TVI-based strain imaging during DbE may facilitate the prediction of myocardial viability but has technical limitations. STE overcomes these but requires… (More)
