Postoperative appearance of tetralogy of Fallot after total correction
and LPA stent placement in a 17-year-old girl. (A) Sagittal
oblique maximum intensity projection (MIP) CT image shows a VSD patch
(black arrow). (B) Axial oblique MIP CT image shows grossly
dilated RA and RV. (C) Sagittal oblique MIP CT image shows
dilated RV and RVOT. A patent stent is seen in the MPA extending into
the LPA. Stent placement was performed to relieve recurrent LPA ostial
stenosis. (D) Axial oblique MIP CT image shows a patent
stent in the distal MPA extending into the LPA. There is proximal
migration of the stent with fracture in stent scaffold integrity (red
arrow), suggesting stent fracture. Ao = aorta, LPA = left pulmonary
artery, LV = left ventricle, MPA = main pulmonary artery, RA = right
atrium, RPA = right pulmonary artery, RV = right ventricle, RVOT = right
ventricular outflow tract, VSD = ventricular septal defect.
