Successful pregnancies are possible after the complete surgical repair of Truncus Arteriosus. Careful testing before pregnancy and close medical monitoring throughout are necessary, however.

It should be borne in mind that there is a high incidence of genetic abnormalities in patients with this defect (involving chromosome 22q11). Therefore, genetic testing is recommended for all prospective mothers.

Anyone with congenital heart disease, repaired or non-repaired, should consult with their cardiologist prior to becoming pregnant to review the risks.
