Patients with congenital cyanotic heart disease and pregnancy have been classified as "unfavorable risks."1-3 Thus, according to some authorities,1-4 they should be aborted in the first trimester. With the development of special surgical techniques in diagnosis and surgery over the past 15 years, patients with congenital heart disease who formerly died are now in the child-bearing age and may continue with pregnancy safely. The question of how well these patients tolerate pregnancy has not been satisfactorily established, and the accepted prognosis may have to be revised.
Very few cases of normal pregnancy and successful delivery in surgically treated tetralogy of Fallot have been reported in the literature. However, there are probably other cases not reported at present. The following case report is submitted, and we hope that others will also publish their experience, so that a significant series will permit a better study of this problem.
