Abstract

Objective To assess the value of fetal heart rate (FHR) measurements in predicting spontaneous fetal loss in pregnancies scheduled for chorionic villus sampling (CVS). Design A prospective descriptive study. Setting Two hospital departments of obstetrics and gynaecology in Israel. Subjects 114 women between 9 and 11 weeks gestation scheduled for chorionic villus sampling (CVS). Interventions Fetal heart rate was measured by transvaginal Doppler ultrasound and compared with a monogram established from 75 fetuses. Whenever a normal FHR was recorded, CVS was performed immediately. Results 106 women had a normal FHR and underwent CVS; two of these pregnancies ended in miscarriage. In five pregnancies no fetal heart beats could be identified and fetal death was diagnosed. In three pregnancies an abnormal FHR was recorded and CVS was postponed; all three pregnancies ended in miscarriage within 2 weeks. Conclusion Determination of FHR correlated with crown‐rump length could be useful in predicting spontaneous miscarriage before performing any invasive procedure late in the first trimester.
