Figure 2

The preoperative CT scan and 3-D reconstruction. A: CT scan showed that the dorsal strut seemed to lie over the bifurcation of pulmonary trunk (single arrow). Its dorsal tip seemed to have perforated the left upper lobe bronchus (double arrow). B: The ventral strut lay behind the sternum. According to the traditional CT scan images, it was not apparent whether the struts perforated into the right ventricle or RVOT due to metal artifact. C and D: The following 3-D reconstruction of CT scan images revealed intracardiac migration of the two struts. The single arrow marked the dorsal strut, which perforated RVOT. The double arrow marked the ventral strut, which perforated into the right ventricle.
