At 24 weeks gestational age, a term female infant was diagnosed with complex congenital heart disease. The antenatal cardiac diagnosis was uncertain and included univentricular heart. Following delivery, the child remained well and was normally saturated. Echocardiography and angiocardiography revealed an unusual relationship between atria and ventricles.
