Nine pregnancies in five women after total correction of the tetralogy of Fallot (TOF) are reported. In four women, further corrective operations were necessary in order to achieve class I functional capacity. Our management of the patients during pregnancy, labor and puerperium is described, and some simple rules are stressed. We suggest that improved feto-maternal outcome, in our series, may be related to the recorrective surgery of residual defects after one stage total correction of TOF, as well as to close surveillance by monitoring of perinatal and hemodynamic aspects of these patients.
