Comprehensive evaluation of left ventricular deformation using speckle tracking echocardiography in normal children: comparison of three-dimensional and two-dimensional approaches

Abstract

Highlights 1. Adequate feasibility of 3D STE in pediatrics; comparable to 2D STE. 2. Significantly shorter acquisition and analysis time for 3D GLS compared to 2D GLS. 3. Excellent agreement between 3D and 2D LV GLS and moderate to poor agreement between regional strain values. 4. Excellent inter and intra-observer reproducibility for GLS by the two techniques, and fair to poor reproducibility for regional strain (higher for apical than basal regions).
