) perimembranous ventricular septal defect (VSD). There was a bidirectional ventricular septal defect shunt, with left-to-right predominance. Right-sided aortic arch. Due to difficult anatomical conditions, no conclusion was made regarding the morphology of arterial branches of the arch (Fig. 2, Fig. 3, Fig. 4. Fig. 5, Fig. 6, Fig. 7 and Fig. 8). Figure 2, Fig. 3, Fig. 4 and Fig. 5 show a series of upper mediastinal vessel sections in a plane similar to transverse plane – horizontal.
