Abstract
Criss-cross heart is a rare congenital cardiac anomaly characterized by the crossing of two ventricular inflow streams. We have demonstrated the utility of 4-dimensional color Doppler rendering in diagnosing the criss-cross heart in a fetus. Four-dimensional color Doppler rendering can demonstrate the relative direction of intracardiac blood flows and facilitate recognition of the crossover of inflow streams in the same plane, confirming the criss-cross heart diagnosis in the fetus.

Movie 1. Two-dimensional color Doppler (left) and 4-dimensional color Doppler rendering (right) fetal echocardiography at 30 weeks of gestation. Four-dimensional color Doppler rendering showed simultaneously crossing bloodstreams of the 2 inlets in the transverse plane of the fetal chest, resulting in the criss-cross appearance. The spatial arrangement of the 2 atrioventricular inlets can be recognized clearly. (MP4 912 KB)
