Radionuclide angiography in congenitally corrected transposition of the great vessels in an adult.
The case of a 34-yr-old man with congenitally corrected transposition of the great vessels is described. Both first-pass and equilibrium radionuclide angiographic data were acquired and demonstrate the value of both studies in delineating the ventricular inversion and the transposed great vessels that are characteristic of this disorder. In addition to the anatomic information, the ejection fractions of the venous and systemic ventricles at rest and during exercise, the lack of any left to right shunt, and the presence of systemic A-V valve insufficiency can all be obtained from the scintigraphic data.
