Key result
Four LV untwist patterns in healthy youth link to systolic rotation but not age or mass.
Why the study?
The study was conducted to assess left ventricular untwist in healthy children and adolescents born full-term.
Cross-Sectional (n=108)
This study characterizes four types of left ventricular untwist in healthy children and adolescents, which correlate with systolic rotation but not with age or myocardial mass.
Supports association of LV untwist with systolic rotation in healthy youth; leaves open prognostic value and disease associations.
The aim of the study is to assess the left ventricle (LV) untwist in healthy children and adolescents born fullterm. Materials and methods. The analysis was carried out in 108 healthy children aged 2 months to 18 years, born full-term. LV untwist is assessed using Speckle Tracking Imaging at the basal and apical level. Results. Four types of LV untwist were identified in children and adolescents. We did not find relation between LV untwist and age, nor with LV index spherical in systole and diastole, LV myocardial mass. The relationship between LV untwisting and LV rotation in systole at basal and apical segments was revealed. Conclusion. The described features of LV loosening are apparently associated with processes of postnatal growth and maturation of heart tissues in children and adolescents.

Pavlyukova et al. (2018) conducted a cross-sectional in Healthy children and adolescents born full-term (n=108). Speckle Tracking Imaging was evaluated on Left ventricle (LV) untwist. Four types of left ventricular untwist were identified in healthy children and adolescents, showing a relationship with LV rotation in systole but no relation to age or LV myocardial mass.
