Tc-99m-pyrophosphate accumulation on prosthetic valves.
Tc-99m-stannous pyrophosphate myocardial imaging has been one of the most effective and sensitive procedures for detection of acute myocardial infarction since Bonte et al introduced it in 1974. However, many causes of false-positive studies have also been reported since then. Presented here is an abnormal case of a patient with aortic and mitral valve replacement.
