Pregnancy after fontan repair of complex congenital heart disease

Aust N Z J Obstet Gynaecol. 2001 Nov;41(4):464-8. doi: 10.1111/j.1479-828x.2001.tb01334.x.


We describe four successful pregnancies in three women who had previously had a Fontan repair for congenital heart disease. Each pregnancy resulted in a live birth and there was no maternal mortality The infants were premature, being delivered at 26, 30 and 35 weeks, and weighing 1,020, 1,333 and 1,930 g respectively The fourth infant was born at 32 weeks and no birthweight is available. Maternal complications occurred and were those anticipated after a Fontan repair. Two mothers required treatment for supraventricular arrhythmias (atrial flutter and fibrillation). Ventricular failure was present in two mothers and required ongoing drug treatment. Raised systemic venous pressures caused peripheral oedema in two mothers and hepatomegaly and ascites in one mother. The physiology, potential complications, anaesthetic concerns and drug treatment in pregnancy after Fontan repair are discussed.
