Abstract

In a patient with sporadic atypical chest pain associated with dyspnea, stress Tc-99m MIBI imaging showed normal perfusion and inferoposterior hypoperfusion on the resting study. Although this reverse perfusion pattern was considered artifactual, the patient later had an acute myocardial infarction involving the same areas. Postinfarction stress Tc-99m MIBI imaging showed e nonreversible defect in the same area that, in the earlier study, showed a reverse perfusion pattern. The authors hypothesize that partial stenosis of the related artery with some nontransmural myocardial necrosis at the time of the initial study may be a possible cause of this peculiar Tc-99m MIBI perfusion pattern.
