Summary
Real-time 3D speckle-tracking echocardiography (RT3DSTE) is feasible and reproducible for assessing left ventricular (LV) rotation, twist, and torsion in children. While LV rotation and twist show no age-related changes, torsion gradually decreases with age in this pediatric cohort.
Area of Science:
- Cardiology
- Pediatric cardiology
- Medical imaging
Background:
- Assessing left ventricular (LV) function in children is crucial for diagnosing and managing heart conditions.
- Real-time 3D speckle-tracking echocardiography (RT3DSTE) offers a novel approach to evaluate LV mechanics.
- Previous studies have not fully established the feasibility, reproducibility, and maturational changes of LV rotation, twist, and torsion using RT3DSTE in pediatric populations.
Purpose of the Study:
- To evaluate the feasibility, reproducibility, and maturational changes of LV rotation, twist, and torsion using RT3DSTE in healthy children.
- To establish normal ranges for these parameters across different age groups.
- To determine the potential of RT3DSTE for quantitative assessment of pediatric heart diseases.
Main Methods:
- A prospective study involving 347 healthy children (birth to 18 years) was conducted using RT 3D echocardiography (3DE).
- LV rotation, twist, and torsion were measured off-line using specialized software with manual landmark selection and semi-automated tracking.
- Feasibility was assessed based on successful measurement acquisition, and reproducibility was evaluated through intra- and inter-observer variability analyses.
Main Results:
- RT3DSTE analysis of LV rotation, twist, and torsion was feasible in 88.5% of the subjects.
- No significant correlation was found between LV rotation or twist and age, height, weight, BSA, or heart rate.
- A modest but statistically significant correlation was observed between LV torsion and age, with torsion decreasing as age increased. Intra- and inter-observer variabilities ranged from 7.3% to 15.7%.
Conclusions:
- RT3DSTE is a feasible and reproducible method for assessing LV rotation, twist, and torsion in the pediatric population.
- LV rotation and twist do not exhibit maturational changes in children, whereas LV torsion shows a decrease with age.
- Further research is needed to validate RT3DSTE for sensitive and quantitative evaluation of congenital and acquired pediatric heart diseases.

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame. The absolute velocity of point B is determined by adding the absolute velocity of point A, the relative velocity of point B in the rotating frame, and the effects caused by the angular velocity within the rotating frame.

Three-dimensional strain analysis is crucial for understanding how materials deform under stress, particularly in elastic, homogeneous materials. This method employs principal stress axes to simplify complex stress states into more understandable forms. Subjected to stress, a small cubic element within a material either expands or contracts along these axes, transforming into a rectangular parallelepiped. This transformation effectively illustrates the material's deformation. The principal...
