Area of Science:

  • Cardiovascular Anatomy
  • Developmental Biology
  • Medical Imaging

Background:

  • Accurate morphometric data of fetal and perinatal cardiovascular structures are essential for understanding congenital heart disease.
  • Previous studies have often lacked comprehensive measurements or advanced modeling techniques.

Purpose of the Study:

  • To conduct a detailed morphometric analysis of the great arterial trunks and associated vessels in fetuses and newborns.
  • To develop anatomo-geometric models and establish normal morphometric parameters for clinical application.

Main Methods:

  • Morphometric measurements of 17 parameters in 496 fetuses and newborns (60-5000g).
  • Development of anatomo-geometric models and use of stereometric formulas for volume calculations.
  • Analysis of correlations between body weight and morphometric parameters using regression equations.

Main Results:

  • Established normal ranges (minimum, normal, maximum) for 17 cardiovascular parameters.
  • Quantified relationships between aortic isthmus, left ventricular, arterial duct, and pulmonary trunk volumes.
  • Identified distinct dimensional relationships between the aortic isthmus and arterial duct.

Conclusions:

  • The study provides critical normative morphometric data for fetal and perinatal cardiovascular development.
  • These findings have direct clinical and surgical relevance for managing congenital cardiovascular disorders.
  • The established regression equations and models can aid in precise diagnosis and treatment planning.
