THE HEART
Fig. 5.16 Tetralogy of Fallot, 22 weeks. A membranous
ventricular septal defect is clearlyseen. An
overriding aorta is also diagnosed; it is wider than
the pulmonarytrunk.
Fig. 5.17 Tetralogy of Fallot. Outflow tract of the

This differs from the normal findings in that the
diameter of the aorta (AO) is greater than that of the
pulmonarytrunk (Tp).
