Fetal Echocardiography

Impact of cardiac anomalies

  • 15 % of abortions are due to cardiac anomalies.
  • Incidence of aneuploidy is 20 % in C A
  • 20 % of neonatal deaths due to malformations are due to CA.
  • 50 % of infant deaths due to malformations are due to CA.

Why is cardiac evaluation mandatory ?

  • Cardiac anomalies are commonest anomalies ( 1/3rd ) found at birth.
  • Prevalence is 5 in 1000 live births.
  • Many of these have good prognosis, if they are detected antenatally and can be treated immediately after birth.
    “Only 30 % of cardiac anomalies are detected in high risk group, where as 70 % are detected in the low risk group.” — Asim Kurjak.
  • Screening is Must at 18 – 22 weeks.

This makes fetal echocardiography absolutely mandatory.
Efficacy of fetal echocardiography

  • 4 Chamber view diagnoses 45 % of cardiac anomalies.
  • The outflow tracts diagnose another 25 %.
  • Approximately 30 % are still missed.
  • USG sensitivity for cardiac anomalies is > 90%, with specificity of almost 100% with STIC.

Early hypoplasias can be made out very clearly by colour and power doppler and also by inversion. (Picture 2)

  • Rhabdomyoma – cardiac tumour (Picture 4)
