The Use of Sonography in a Mother and Fetus With Concordant Truncus Arteriosus

Abstract

Reported pregnancies in women with repaired truncus arteriosus are rare. As a result of improved surgical techniques, more women with conotruncal defects are now reaching reproductive age. Multifactorial inheritance rather than single gene mutation is the causative agent of most congenital heart disease. The environment can play an important and varied role in direct transmission, particularly in incidences where genes predispose a defect. This may be one of the first reported cases discussing a pregnant mother with repaired truncus arteriosus and her fetus, prenatally diagnosed with a concordant truncal defect.
