Objective: We present HDlive Flow features of transposition of great arteries (TGA) with ventricular septal defect (VSD), pulmonary stenosis (PS), and persistent left superior vena cava (PLSVC) at 21 weeks and 2 days of gestation. Case description: HD-flow suggested parallel positioning of great arteries exiting the right ventricle, VSD, and PLSVC. HDlive Flow (Silhouette) clearly revealed an aorta exiting the right ventricle and a small pulmonary artery (PS) exiting the left ventricle in parallel. Pulmonary valvar stenosis was also suspected. A blood vessel (PLSVC) on the left side of the small pulmonary artery was noted. HDlive Flow Silhouette with spatiotemporal image correlation clearly showed a shunt flow stream from the right to left ventricle through VSD. Conclusion: HDlive Flow (Silhouette) may provide additional, useful information for the precise prenatal assessment of complex TGA.
