Video 44.9 Normal heart at 12 weeks GA
Normal heart at 12 weeks GA. Structurally normal 4-chambered heart in a 12-week fetus using transabdominal imaging (9 MHz linear probe). The sweep begins showing a symmetrical 4-chambered heart. Fetal left is to the right of the image showing levocardia. The clip then sweeps cranially to first show the left outflow tract (aorta) followed by the right outflow tract (pulmonary artery) that arises more anteriorly. Crossing of the great vessels is confirmed. There is qualitatively normal biventricular systolic function.
