Objective: To investigate the clinical significance of 3-vessel subsequence view in prenatal screening and diagnosis of fetal congenital heart disease.
Methods: The 3-vessel subsequence view of 231 fetuses with congenital heart disease was obtained with Sequoia 512, Voluson 730 and E8 color Doppler ultrasonographic diagnostic system.
Results: Of the 231 consecutive fetuses with congenital heart defects (CHD), 169 (73%) had at least 1 abnormality on the 3-vessel subsequence view. When ventricl septal defects and so on were excluded, the detection rate increased to 91%. Some defects had several abnormalities visualized at the 3-vessel subsequence view.
Conclusion: The 3-vessel subsequence view has high detection rate in identifying the presence of CHD.
