Key result
Fetal echocardiography using the four-chamber view and additional views provides a step-wise approach for evaluating fetal cardiac anatomy and function during obstetric anomaly scans.
Why the study?
To provide a step-wise process for radiologists and pediatric cardiologists to become more familiar with evaluating fetal cardiac anatomy using the four-chamber and additional views.
This review provides a structured approach to fetal echocardiography, emphasizing the importance of standard and additional views for detecting cardiac anomalies.
Supports standardized fetal cardiac screening in anomaly scans; leaves open prospective validation of detection rates.
This article presents a step-wise process to evaluate fetal cardiac anatomy by the radiologist and the pediatric cardiologist, to become more familiar while assessing the four chamber view including the views for the outflow tracts. The additional views include bicaval view, three-vessel view (3VV), three- vessel trachea view (3VT), and aortic arch view. M-mode, color flow mapping and pulse Doppler ultrasound are useful to evaluate cardiac anatomy and function. If the heart does not look normal, the patient should be referred to dedicated fetal echo centre for detailed evaluation. Ductus venosus Doppler, cardiovascular profile score and visualization of thymus in 3-vessel view have also been described in brief.
