Video 44.1 Situs sweep and orientation
Situs sweep and orientation. Initially the fetus is seen in its long axis with the transducer orientation groove oriented towards the fetal head. Fetal head is initially right of screen. The transducer is rotated 90° clockwise then showing the fetus in a transverse plane. With this maneuver, the fetal left will always be to the right of the screen at the end of the probe rotation. In this clip there is levocardia with a left-sided stomach. Even in this orientation sweep a 4-chambered heart and a normal 3-vessel view is seen.
