Schematic drawing of the fused heart of case 3. There were two ventricles and two atria. A normally located left aorta arose from the left ventricle. At the right atrium small pulmonary veins were seen. From the right ventricle the second, relative smaller, right aorta, right pulmonary trunk and a right ventricle outflow tract (RVOT) of the left pulmonary trunk were seen; this could be interpreted as a triple outflow right ventricle (TORV). There were two ducti arteriosi. On the right side no clear pulmonary veins were seen. There was a ventricular septal defect (VSD) resulting in a complex haemodynamic situation
