Pregnancy is contraindicated in uncorrected tricuspid atresia. Even following palliative surgery with the Fontan procedure, only four pregnancies have been reported. ⋯ Five similar pregnancies, including this one, have been reported. Although all were successful, three infants were preterm and two growth retarded. This observation suggests that for these patients, pregnancy must be monitored closely even though the mothers may be hemodynamically stable.
