WebANOMALIES OF SEPTATION OF THE BULBUS CORDIS Persistent truncus arteriosus: failure of the aorticopulmonary septum to develop and divide the truncus into an aorta and pulmonary trunk. Also may see defective fusion of the bulbar ridges. Most commonly see one vessel giving rise to an aorta pulmonary trunk, but other variations are possible WebDuring the fifth week, ridges of the subendocardial tissue form in the bulbus cordis. Similar ridges also form in the truncus arteriosus and are continuous with those in the bulbus cordis. The spiral orientation of the ridges results in a spiral aorticopulmonary septum when these ridges fuse.
