Figure 8: The cartoon shows some of the potential univentricular atrioventricular connections. In reality, these can exist with any arrangement of the atrial appendages (upper row), with double inlet, absent right, or absent left atrioventricular connections (middle row), and with dominant left or right ventricles, or solitary and indeterminate ventricle (bottom row). The possibilities are illustrated with usual arrangement of the atrial appendages simply for convenience, while the examples in the bottom row are shown only for double inlet ventricle. The same variation in ventricular morphology exists for hearts with absence of one atrioventricular connection. There is further variability with regard to the position of the incomplete ventricle, and with ventriculo-arterial connections, and so on. These hearts, therefore, exemplify the need for full sequential segmental analysis and description
