[Normal pregnancy duration after maternal Fontan operation of univentricular heart].

Up to now pregnancy in patients with a previous Fontan operation for definitive palliation of a univentricular heart has been regarded as contraindicated. Two cases of a pregnancy after Fontan operation and univentricular heart were published in the literature. In a single case a successful delivery of the fetus could be achieved. The presented case is the third published pregnancy after Fontal operation and the second with a successful fetal outcome. The 30 years old patient was born with a univentricular heart of right ventricular type with tricuspid and pulmonary atresia and persisting arterial duct. After bilateral Blalock Taussig anastomoses (1966) and modified Waterston-Cooley-anastomosis (1974) a primary existing cyanosis could be improved. The cyanosis was completely abolished after definitive repair with the Fontan operation at the age of 17 (1980). The course of pregnancy and its surveillance is reported. In the 32nd week of gestation cesarean section had to be performed because of threatening cava compression. A healthy female fetus of 1275 g was delivered. The mother's postoperative recovery was uneventful. Meanwhile the neonate and the mother have been discharged and are in good clinical condition.
