Video 44.2 Four-chamber view sweeping to 3-vessel view
Four-chamber view sweeping to 3-vessel view. Normal fetal heart at 18 weeks starting with the 4-chambered view. The fetal left is to the right of the screen showing levocardia in this example. The transducer is tilted superiorly towards the fetal head showing the left ventricular outflow tract then right ventricular outflow tract and finally finishing with the normal 3-vessel view (pulmonary artery, aorta and SVC from left to right of the fetal chest). A symmetrical 4-chambered heart is seen with atrioventricular and ventriculoatrial concordance. On the initial image pulmonary veins are seen entering the left atrium.
