Anaphylactic Shock Due to Technetium (99mTc)-Tetrofosmin During Myocardial Perfusion Scintigraphy: A Case Report

Abstract

Myocardial perfusion scintigraphy is a popular minimally invasive method for evaluating chronic coronary disease (CCD). We performed myocardial scintigraphy to assess CCD in a 74-year-old man with a history of allergy to contrast media. The patient developed anaphylactic shock immediately after the administration of the technetium ( 99m Tc)-tetrofosmin preparation. This is the first report of anaphylactic shock due to 99m Tc-tetrofosmin administration during myocardial perfusion scintigraphy.
