Tetralogy of Fallot is the most common cyanotic congenital cardiac lesions. Although pregnancy in patients with corrected tetralogy of Fallot usually have a satisfactory outcome, there may have maternal cardiovascular complications. ⋯ There are more risks for the binomial in patients with uncorrected tetralogy of Fallot and in those operated with significant residual lesions. A greater anatomical impact was significantly correlated with major hemoglobin and minor oxygen saturation, which are the most important risk factors for adverse fetal outcomes.
