TETRALOGY OF FALLOT
Fig. 5.19 Tetralogy of Fallot with absent pulmonaryvalve:
the pulmonarytrunk (Tp) branches into
the right (dextra, Apd) and left (sinistra, Aps) pulmonaryarteries.
Both are significantlydilated. The ductus
arteriosus (Botallo’s duct) is not seen.
Fig. 5.20 Tetralogy of Fallot. Color flow mapping
of the same case. In the diastolic phase, a large
amount of blood flows back into the right ventricle
through the dysplastic pulmonary valve.
Fig. 5.21 Tetralogy of Fallot. Pulsed Doppler ultrasound,
showing blood flowing in both directions
through a dysplastic pulmonary valve.
