Video 24.10 Transposition of the great arteries - VSD with anterior malalignment
Transposition of the great arteries with perimembranous-to-outlet ventricular septal defect (VSD) with anterior malalignment. On this long-axis view the parallel orientation of the great vessels is demonstrated. A perimembranous-to-outlet VSD is visualized with the outlet septum deviated anteriorly into the right ventricular outflow tract.
