Figure 16.

Virtual dissection (Panel A) and endocast reconstruction (Panel B) of a patient with repaired tetralogy of Fallot with moderate right ventricular outflow tract obstruction. Both images are viewed in a right anterior oblique plane. The virtual dissection image (Panel A) demonstrates a discrete ridge at the pulmonary sinutubular junction (green arrowhead). An angiogram was obtained in similar plane (Panel C) during cardiac catheterization confirming the anatomy, prior to placing a transcatheter pulmonary valve to relieve the obstruction.
