Note the large arterial duct between the pulmonary component of the common trunk and the descending aorta. In Image #2 the common arterial trunk has been opened and is viewed anteriorly. The pulmonary component is dominant with the small aortic component marked with the black dots. The truncal valve consists of three leaflets and there is a muscular, subarterial ventricular septal defect (interventricular communication) with a postero-inferior muscular bar (caudal arm of the septomarginal trabeculation) separating the arterial from the atrioventricular valve. (yellow Y – septomarginal trabeculation)
