    Abstract

    Introduction

    Tissue deformation imaging enables the objective assessment of regional myocardial deformation assessed by ultrasound-based strain and strain rate. There are two ways to compute myocardial deformation (strain) using echocardiography: One-dimensional tissue Doppler (DTI)-derived strain and two-dimensional (2D) strain derived from B-mode images (speckle tracking, 2D-ST). This study compares the myocardial deformation parameter (i.e., strain) by these two techniques in the perioperative period using transesophageal echocardiography (TEE) in patients undergoing surgery for coronary artery bypass graft (CABG).

    Materials and methods

    We performed preoperative global longitudinal strain (GLS) of left ventricle (LV) using 2D-ST and DTI, three-dimensional (3D) left ventricular ejection fraction (LVEF) and 2D LVEF in a consecutive series of 50 adult patients scheduled for on-pump CABG.

    Result

    There was no difference between 2D and 3D LVEF (p < 0.0001), GLS using 2D-ST and DTI (p-value = 0.0005). The 3D LVEF correlated well with GLS using 2D-ST (r = 0.54, p < 0.0001) and less with tissue Doppler-derived GLS (r = 0.35, p-value = 0.0131).

    Conclusion

    The LV GLS calculated using 2D-ST correlates well with LV GLS derived from DTI using TEE. The LV GLS also correlated well with the 3D LVEF.
