3-vessel subsequence view in prenatal screen and diagnosis of fetal congenital heart disease

Abstract

To investigate the clinical significance of 3-vessel subsequence view in prenatal screening and diagnosis of fetal congenital heart disease. 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. 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. The 3-vessel subsequence view has high detection rate in identifying the presence of CHD.
