Pregnancy and the Rastelli operation.

Background: The aim of surgical correction of congenital heart disease is for the patient to live a relatively normal life, including potential pregnancy and childbirth. The Rastelli repair operation using a valved conduit for certain complex congenital heart lesions has resulted in survival into adult life.

Aims: We reviewed reproductive outcome of 22 women over 18 years of age who were survivors of the Rastelli operation performed between 1977 and 1999.

Results: Six women had a total of 12 pregnancies with six live births. Three women, with complex transposition of the great arteries, developed more severe subaortic obstruction during pregnancy. All required further heart surgery. Delivery was by Caesarean section in three patients and vaginally in the other three. All infants were healthy and free from defects. Two women had tubal ligations because of their cardiac problems.

Conclusions: Women who have had Rastelli repair operation for complex congenital heart disease can have successful pregnancies. Subaortic stenosis can become a problem and should ideally be eliminated before pregnancy. Because of multiple operations, complications and genetic concerns, some women choose not to reproduce. Careful cardiac evaluation before, during and after pregnancy is essential.
