4D ultrasonography, using B-flow imaging and spatiotemporal image correlation, demonstrating tetralogy of Fallot, pulmonary atresia and total anomalous venous return, from a left oblique view of the posterior heart. A confluence of pulmonary veins drains into a vertical vein, resembling a starfish in shape. DAO, descending aorta; DV, ductus venosus; HV, hepatic vein; IVC, inferior vena cava; LPV, left pulmonary vein; RPV, right pulmonary vein.
