Prenatal ultrasonic detection of truncus arteriosus with interrupted aortic arch and truncal valve regurgitation

Abstract

The echocardiographic appearances in a case of persistent truncus arteriosus with aortic arch interruption and truncal valve dysplasia was noted in a 24 week fetus. Elective termination of pregnancy was carried out and all the echocardiographic findings were confirmed by pathological examination suggesting the possibility of accurate prenatal diagnosis of such lesions.
