Background: The congenital heart defects are a very difficult problem in anesthesiology. The most serious problem are cyanotic heart defects which create danger for patient’s life, particularly during non cardiac procedures. There are many controversies around anesthesia and postoperative treatment in those cases because most of congenital heart defects are very complicated. The emergency operations e.g. caesarean section are most dangerous. Tetralogy of Fallot is the most common cyanotic congenital heart defect. The haemodynamic changes which are present immediately after abdominal delivery may result in serious, life-threatening multiorgan complications. Therefore the choice of anesthesia is very difficult.Case Report: The authors present a case report of 38 year old woman with uncorrected tetralogy of Fallot who underwent caesarian section. The epidural anesthesia was performed uneventfully. The postoperative hospitalization lasted seventeen days and the woman was discharged in a relatively good general condition. Conclusions: The epidural anaesthesia is a method of choice in a pregnant woman with uncorrected cyanotic heart diseases.
