Insights

Fetal growth restriction (FGR) impacts pregnancies, causing cardiac issues detectable via ultrasound. Early detection and monitoring using specific ultrasound parameters can identify risks and guide interventions for better outcomes.

Area of Science:

  • Perinatal Medicine
  • Cardiology
  • Medical Imaging

Background:

  • Fetal growth restriction (FGR) affects 7-10% of pregnancies.
  • Cardiac compromise is observed in fetuses and neonates with FGR.
  • Ultrasound plays a crucial role in assessing FGR-related cardiac and vascular changes.

Purpose of the Study:

  • To review ultrasound parameters for assessing cardiac function and vascular health in FGR across different age groups.
  • To highlight the predictive value of feto-placental parameters for perinatal outcomes and later hypertension.
  • To discuss the clinical relevance of these parameters in intervention strategies.

Main Methods:

  • Review of conventional and tissue Doppler imaging in fetal and neonatal FGR.
  • Analysis of sonographic parameters in fetal life, early postnatal, and pediatric periods.
  • Discussion of vascular imaging findings, including arterial stiffness and blood pressure.

Main Results:

  • Fetal sonographic parameters predict adverse perinatal outcomes and later hypertension.
  • Postnatal FGR infants show altered heart morphology and sub-clinical cardiac dysfunction.
  • Vascular imaging reveals thickened, stiffer arteries and elevated blood pressure in FGR individuals, persisting into childhood.

Conclusions:

  • Ultrasound parameters are vital for assessing FGR manifestations from fetal life through childhood.
  • Point-of-care ultrasound aids clinicians in identifying sub-clinical FGR cardiac and vascular changes.
  • These findings support the development and monitoring of targeted interventions for FGR.
