Myocardial Perfusion Scintigraphy in a Patient With Transposition of Great Arteries Post-Atrial Switch Surgery.

We report a case of a 33-year-old woman who underwent stress and rest myocardial perfusion scintigraphy (MPS) to exclude coronary artery disease. MPS images showed an apparent dextrocardia with a right-sided septal wall uptake. The electrocardiograph showed a right axis deviation with dominant R waves at leads aVR and V1.
