“…TDI results from fetus to neonate were similar whether the same or different equipment were used. Recently, Koopman et al [29] reported the inter-machine comparability of TDI parameters in children. They concluded that the agreement between Phillips-derived and GE-derived TDI was reasonable; however, we recommend the same ultrasound system for measurement of serial changes.…”

“…Averaging measurements over multiple beats slightly reduced variability, but it is still unclear if this extra step results in clinically significant gains. In our laboratory we validated the inter-and intra-observer variability of the different functional parameters including TDI and STE measurements [7][8][9]. Longitudinal and circumferential end systolic strain measurements have low inter-and intra-observer variability; however, radial strain and all measures of strain rate are more variable [7].…”

“…Based on our research work on intermachine variability of tissue Doppler and strain measurements [7][8][9], all functional imaging at our laboratory is performed on a machine from a single vendor (Vivid 7 or E9, GE Healthcare, WI, USA). This reduces variability and makes serial comparisons during follow-up easier.…”

Assessment of ventricular function is an important part of every echocardiographic examination. Specific pediatric guidelines on quantification of ventricular function are available, but technology evolves quickly and it generally takes long before newer techniques are integrated into routine clinical practice and are adopted by the guidelines. In the current overview, we would like to present our experience with integrating newer echocardiographic techniques for assessing ventricular function in children using a comprehensive state-of-the-art echocardiographic functional protocol. This protocol is used for specific patient populations such as pediatric patients with cardiomyopathy, post-transplant patients and oncology patients. We present the practical aspects of the protocols, their rationale and how this can be applied in clinical practice.

“…In contrast, speckle tracking is more of a ‘black box’ and the user may not be aware of the precise impact of factors such as computational differences (natural versus Lagrangian strain) or the spatial and temporal resolution of the technique1. Recent work in children has demonstrated the impact of the use of different proprietary software on restudy of the same patient with respect to deformation imaging12, 13. This limits the ease of comparison of results between and within centers.…”
