PREGNANCY AFTER FONTAN OPERATION FOR UNIV ENTRICULAR HEART

Up to now pregnancy in patients with a previous Fontan operation for d efinitive palliation of a univentricular heart has been regarded as co ntraindicated. Two cases of a pregnancy after Fontan operation and uni ventricular heart were published in the literature. In a single case a successful delivery of the fetus could be achieved. The presented cas e is the third published pregnancy after Fontan operation and the seco nd with a successful fetal outcome. The 30 years old patient was born with a univentricular heart of right ventricular type with tricuspid a nd pulmonary atresia and persisting arterial duct. After bilateral Bla lock Taussig anastomoses (1966) and modified Waterston-Cooley-anastomo sis (1974) a primary existing cyanosis could be improved. The cyanosis was completely abolished after definitive repair with the Fontan oper ation at the age of 17 (1980). The course of pregnancy and its surveil lance is reported. In the 32nd week of gestation cesarean section had to be performed because of threatening cave compression. A healthy mal e fetus of 1275 g was delivered. The mother's post operative recovery was uneventfull. Meanwhile the neonate and the mother have been discha rged and are in good clinical condition.
