Fetal echocardiographic screening for congenital heart disease.

During a 30-month period, 7,531 obstetrical ultrasound examinations were performed on 3,624 fetuses at a community hospital. All fetuses were evaluated for congenital heart disease and 16 complex defects were identified. Only two of the cardiac defects had predisposing clinical factors or an elevated serum alpha-fetal protein.

Duplex Doppler sonography of the umbilical arteries: predictive value in IUGR and correlation with birth weight.

Forty-three women with either clinically high-risk singleton pregnancies or a predicted fetal weight less than the 10th percentile were studied in their third trimester by duplex Doppler sonography of the free umbilical artery to assess the associations between umbilical arterial flow resistance and intrauterine growth retardation (IUGR) and birth weight. Test criteria included: the greatest (GRI), mean (MRI), and least (LRI) resistive index. The criterion with the strongest association with IUGR (p = 0.
