ABSTRACT
The development of an acardius in a monozygotic multiple pregnancy has been reported
in more than 200 cases. We present the case of an acardius acephalus in a twin pregnancy
additionally complicated by a serious cardiac malformation of the donor twin (single
ventricle). Antenatal diagnosis and development as well as intrauterine treatment
of the donor twin from 26 to 34 weeks of gestation are described.
