Summary

Foetal cardiology now includes evaluating fetal heart function beyond diagnosing malformations. This involves assessing arrhythmias and circulatory dynamics, even without primary heart disease, to understand fetal hemodynamics.

Area of Science:

  • Foetal cardiology
  • Paediatric cardiology
  • Foetal haemodynamics

Background:

  • Foetal cardiology has evolved beyond diagnosing cardiac malformations.
  • Current practice includes investigating fetal arrhythmias and circulatory function.
  • Understanding normal fetal circulation is key to interpreting observed phenomena.

Purpose of the Study:

  • To describe the functional and dynamic cardiocirculatory evaluation of the fetus.
  • To classify left heart-fetal hemodynamics interactions.
  • To explain the role of normal fetal hemodynamics in understanding observed phenomena.

Main Methods:

  • Classification of left heart/fetal hemodynamics based on myocardial dysfunction.
  • Analysis of primary vs. secondary left myocardial dysfunction related to pre- and afterload.
  • Utilizing understanding of normal fetal circulation hemodynamics.

Main Results:

  • Left heart/fetal hemodynamics interactions are categorized into two main groups.
  • Dysfunction can be primary or secondary to pre- or afterload changes.
  • Normal fetal circulation hemodynamics provide essential context.

Conclusions:

  • Foetal cardiology encompasses functional assessment beyond structural diagnosis.
  • Understanding hemodynamics is crucial for evaluating fetal well-being.
  • The classification aids in comprehending fetal cardiocirculatory dynamics.
