The cardioangiograms revealed structural or hemodynamic abnormalities in 23 patients that were not evident on the 99mTc-pyrophosphate images. In eight cases the results were unexpected prior to scintigraphy. Cardioangiograms also proved helpful in localizing the site of infarction and in ruling out false-positive results in five patients. The role of radionuclide cardioangiography as an adjunct to acute infarct scintigraphy warrants further investigation. © Lippincott-Raven Publishers.
