Background Fetal acardia is a rare anomaly occuring exclusively in monozygotic multiple pregnancies with an incidence of 1:35000 deliveries or in 1% of monozygotic twins. Since 1920, rudimentary developed heart of an acardiac twin, mostly called ‘hemiacardius’ or ‘pseudoacardius’, has been recognized in eigth cases. Four of them have been discovered during autopsy. We are showing a twin pregnancy of a 25‐year‐old woman with a hemiacardiac and a normal fetus, which was conducted in our Maternity Hospital. In the 22nd week of amenorea a suspicion of acardia of a deceased fetus with multiple malformations was expressed for the first time by ultrasound. With help of amniocenthesis we defined a normal male kariotype of a live twin and by ultrasound we carefully observed its morphology and growth. Furthermore, in the course of the pregnancy, mother's coagulation parameters were controlled weekly. In the 33rd week of gestation an extreme polyhydramnios developed, so amniodrainage was performed twice. The pregnancy was finished in the 36th week of gestation with a caesarian section: a live male child – 2330/46 and a hemiacardiac fetus – 2800 g with multiple malformations were born. The live twin was discharged from hospital three weeks later as a healthy baby.
