Insights

This study found no cardiac dysfunction in fetuses with congenital diaphragmatic hernia (CDH) using speckle tracking. Left CDH cases showed increased left ventricular strain, suggesting compensatory changes.

Area of Science:

  • Perinatology
  • Fetal Cardiology
  • Medical Imaging

Background:

  • Congenital diaphragmatic hernia (CDH) is a serious condition affecting fetal development.
  • Cardiac function assessment in fetuses with CDH is crucial for understanding disease impact.
  • Speckle tracking echocardiography offers advanced methods for evaluating fetal cardiac mechanics.

Purpose of the Study:

  • To evaluate cardiac function in fetuses diagnosed with congenital diaphragmatic hernia (CDH).
  • To utilize speckle tracking technology for assessing fetal cardiac contractility in CDH.
  • To investigate potential cardiac dysfunction and its correlation with pulmonary hypoplasia in CDH fetuses.

Main Methods:

  • A case-control study design comparing fetuses with CDH to anatomically normal controls.
  • Speckle tracking software was employed to calculate ventricular peak longitudinal velocity, displacement, and strain.
  • Pulmonary hypoplasia was quantified using the observed/expected lung-to-head ratio (O/E LHR).

Main Results:

  • Thirty-eight fetuses with CDH were analyzed; image quality was sufficient in 83% of cases.
  • Ventricular velocity and displacement showed regional differences, similar to controls.
  • Fetuses with left CDH exhibited increased left ventricular strain compared to controls, with no correlation to O/E LHR. Right CDH showed no significant differences.

Conclusions:

  • No overt cardiac dysfunction was detected in fetuses with CDH, even with concurrent hypoplasia.
  • Increased left ventricular strain in left CDH fetuses may indicate compensatory mechanisms.
  • Speckle tracking is a valuable tool for assessing subtle cardiac changes in fetal CDH.
