Fig. 2B —7-year-old girl with double-outlet right ventricle status
after pulmonary artery banding followed by bilateral bidirectional Glenn
shunts. Catheterization revealed acceptable hemodynamics to proceed with
Fontan procedure. MDCT was conducted to assess for branch pulmonary artery
distortion, assess for aorta-to-pulmonary artery or venoatrial collaterals,
and review caval–pulmonary artery connections. Coronal oblique
color-coded volume-rendering with clip plane editing shows that left-sided
Glenn anastomosis, from left superior vena cava (LSVC) to left pulmonary
artery (LPA), is unobstructed and left pulmonary artery is of a good size. AO
= aorta.
