Antenatal assessment of congenital heart disease and associated anomalies by ultrasound has improved perinatal care. Fetal cardiovascular MRI and fetal brain MRI are rapidly evolving for fetal diagnostic testing of congenital heart disease. We give an overview on the use of fetal cardiovascular MRI and fetal brain MRI in congenital heart disease, focusing on the current applications and diagnostic yield of structural and functional imaging during pregnancy. Fetal cardiovascular MRI in congenital heart disease is a promising supplementary imaging method to echocardiography for the diagnosis of antenatal congenital heart disease in weeks 30–40 of pregnancy. Concomitant fetal brain MRI is superior to brain ultrasound to show the complex relationship between fetal haemodynamics in congenital heart disease and brain development.

We report a 13-week-old female fetus with early onset fetal akinesia deformation sequence (FADS) and hydranencephaly. In a previous pregnancy, the same ultrasonographic findings were noted at 13 weeks. Fetopathological examination of both female fetuses confirmed FADS with severe arthogryposis, multiple pterygia, and muscular hypoplasia. Neuropathological examination showed massive cystic dilatation of the cerebral ventricles (hydranencephaly) with calcification of the basal ganglion and brain stem and a proliferative vasculopathy throughout the central nervous system. The findings in the two female siblings document the earliest echographic diagnosis of hydranencephaly, Fowler type, and this observation further supports autosomal recessive inheritance of this distinct type of hydranencephaly. © 2002 Wiley-Liss, Inc.

We report the second trimester prenatal diagnosis of severe symmetrical limb deficiencies with posterior fossa cyst and cardiac anomaly in a female fetus. Fetopathological examination revealed additional anomalies: renal-hepatic-pancreatic dysplasia, cleft palate, and Müllerian duct anomaly. The spectrum of congenital malformations in the present observation is difficult to classify into a single syndrome entity and presents an overlap with several syndromes: Roberts syndrome, Goldston syndrome, and renal-hepatic-pancreatic dysplasia. © 2001 Wiley-Liss, Inc.

We present further evidence for autosomal recessive inheritance of the bilateral tibial agenesis/ectrodactyly dysostosis. A consanguineous Turkish couple gave birth to three children with malformations. The first, a boy, died neonatally of pulmonary hypertension with congenital alveolar capillary dysplasia and also had tibial agenesis and ectrodactyly. A second child, a girl, died after birth with the same abnormality of the lungs without skeletal malformations. After the birth of three unaffected children, echographic examination at 15 weeks of gestation in the sixth pregnancy documented agenesis of tibiae and symmetrical ectrodactyly of hands and feet. Autopsy did not show additional malformations, and lung development was normal for gestational age. This observation also confirms the autosomal recessive inheritance pattern of congenital alveolar capillary dysplasia. © 2001 Wiley-Liss, Inc.

We present a retrospective study of the frequency and type of associated malformations and chromosomal anomalies in 42 consecutive cases of congenital diaphragmatic hernia (CDH) diagnosed in utero during the period from 1985 to 1999. In 26% (11/42) of the cases, associated malformations were detected. Chromosomal anomalies were present in 9.5% (4/42). In this group of 15 cases (15/42 = 36%) with associated malformations or chromosomal anomalies, all cases, except one, had prenatal sonographic evidence of additional problems. The survival rate of fetuses with CDH and associated malformations or chromosomal anomalies was poor (1/15). Therefore, the overall survival rate of in utero-diagnosed CDH was only 31% (13/42), while isolated left CDH had a survival rate of 52% (12/23). The in utero diagnosis of CDH implies a detailed echographic examination to exclude additional anomalies. The risk for a syndromal or chromosomal malformation becomes small when no additional anomalies are seen on ultrasound.

Holoprosencephaly is a cerebral anomaly associated with a 13q deletion. We present a case of alobar holoprosencephaly which was diagnosed at 20 weeks gestation and where the fetal karyotype showed a 13q deletion.
