Validation of 3-dimensional speckle tracking imaging to quantify regional myocardial deformation.


BACKGROUND Three-dimensional speckle tracking imaging (3D-STI) has been introduced to assess regional left ventricular (LV) myocardial function. This study was designed to validate LV strain measurements by 3D-STI against data obtained by sonomicrometry. METHODS AND RESULTS In each of 10 anesthetized sheep, sonomicrometry crystals were implanted on the… (More)
