Abstract
The article is devoted to the study of the left ventricular (LV) rotation at the level of the mitral valve, papillary muscles, and the apex in healthy children and adolescents using Two-Dimensional (2D) Speckle Tracking Imaging. Four types of LV twist were identified in children and adolescents. Adult type (I) of the LV twist was observed in 67.06% of cases. Child types (II, III) were found in 23.52%. Type of negative LV rotation was observed in 9.41%.
