Embryologically, the common arterial trunk (CAT) is due to the failure of septation by the major outflow cushions. This invariably leads to the presence of an associated large juxta-arterial ventricular septal defect. Overriding of the ventricular septum leads to its biventricular origin in more than 2/3rd of cases. Uncommonly, CAT may be associated with an intact ventricular septum (IVS) and univentricular origin. We describe an infant with CAT, intact IVS, hypoplastic right ventricle, and Ebstein's anomaly of the tricuspid valve who presented to us and palliated successfully. The embryological mechanisms are discussed in this report.
