Coarctation of the aorta demonstrated by a radionuclide first-pass flow study using tc-99m tetrofosmin.

A 46-year-old woman with a history of myocardial infarctions and cerebral vascular accidents was examined for chest pain and shortness of breath. Because physical examination was suggestive of coarctation of the aorta, a first-pass study of the aorta was obtained at the time of myocardial perfusion scintigraphy. Subsequently, coarctation of the aorta was demonstrated on first-pass myocardial perfusion scintigraphy, magnetic resonance imaging, transesophageal echocardiography, and aortic root angiography. The myocardial perfusion scintigraphic images show that if coarctation of the aorta is a diagnostic consideration, inclusion of a first-pass study of the aorta at the time of myocardial perfusion scintigraphy is a useful addition to standard imaging protocols.
