Hypothesis
There are gender differences in atrial volumes and derived parameters in children and adolescents.
Conclusion
The study established age and gender specific reference percentiles for atrial size and function from ages 6 to 18.
Supporting Evidence
- Maximal right atrial volume for girls was 53.3 ml/m2 and for boys was 58.1 ml/m2.
- Minimal right atrial volume for girls was 23.2 ml/m2 and for boys was 27.0 ml/m2.
- Maximal left atrial volume for girls was 44.2 ml/m2 and for boys was 46.7 ml/m2.
- Minimal left atrial volume for girls was 19.2 ml/m2 and for boys was 21.5 ml/m2.
- Cyclic volume change was higher for boys, but emptying fraction was higher for girls.
Takeaway
Boys and girls have different sizes and functions of their heart's atria as they grow up, and this study helps us understand those differences better.
Methodology
Healthy children and adolescents were enrolled, and 2D imaging was used to measure atrial volumes and calculate related parameters.
Participant Demographics
Healthy children and adolescents aged 4.4 to 20.3 years, mean age 12.4 years.
