Assessment of left ventricular systolic function by deformation imaging derived from speckle tracking: a comparison between 2D and 3D echo modalities

Abstract

Three-dimensional STE allows accurate and faster analysis of deformation when compared with 2D STE and might represent a viable alternative in the evaluation of global LV function.

Assessment of Biventricular Function by Three-Dimensional Speckle-Tracking Echocardiography in Secondary Mitral Regurgitation after Repair with the MitraClip System

“…34 The superiority of 3D STE over 2D STE for the evaluation of all three components of LV deformation (GLS, GCS, and GRS) has been questioned. 35 The 3D mode has good reproducibility as an automated method, as shown by the lower intraobserver and interobserver variability, it avoids foreshortening of apical views, it consumes less time in data acquisition, and an helps solve the problem of out-of-plane motion present in the 2D modality, tracking the motion of speckles in all three dimensions. However, this advantage is achieved at the expense of a lower volume rate, which might alter the correlations with measurements obtained by 2D STE.…”

“…La reciente publicació n de valores de referencia con ecocardiografía speckle tracking tanto bidimensional 33 como tridimensional 34 pueden fomentar su implementació n en la rutina clínica. El continuo desarrollo de esta té cnica debido a la aparició n de nuevas tecnologías basadas en la deformació n tridimensional ha seguido dando sus frutos; destaca su utilidad para el estudio de la funció n ventricular derecha 35 y ha dado lugar a la realizació n de diversos estudios comparativos con la té cnica bidimensional en busca del pará metro má s sencillo y reproducible, con resultados en ocasiones contradictorios [36][37][38] .…”
