Conotruncal abnormalities are those which include abnormalities of the great arterial connections and arrangement. They include Tetralogy of Fallot, Pulmonary atresia with ventricular septal defect, Double outlet ventricles, Truncus arteriosus, Transposition of the great arteries and Interrupted aortic arch with ventricular septal defect.

Whilst these lesions form a relatively diverse group, from a fetal screening perspective all can be identified with outflow tract and 3 vessel tracheal view screening views.

This session will highlight an approach to diagnosis of conotruncal lesions from screening to advanced fetal echo techniques aimed at identifying important factors in counselling and ongoing management.
