Abstract
A 58-year-old male was admitted to the emergency room with an acute inferior ST-elevation myocardial infarction (Figure 1). His coronary risk factors included arterial hypertension and hypercholesterolemia. Emergency percutaneous coronary intervention (PCI) was performed with stenting of the occluded right posterolateral branch with a 2.5×18 mm Zotarolimus-eluting stent (Medtronic, Minneapolis, Minn.) (Figure 1A and 1B). The left ventricular ejection fraction was 41% and the postinterventional TIMI flow was grade II with reduced flow of the entire right coronary artery (RCA) and persistent ST elevation within the inferior leads. The maximum creatine kinase level was 1863 U/L and peaked 36 hours after PCI. 99mTechnetium-sestamibi scans to assess coronary perfusion immediately before and 6 days after intervention (Figure 2) revealed no myocardial salvage subsequent to PCI within the inferior wall. Contrast-enhanced coronary magnetic resonance angiography with the use of 0.2 mmol/kg gadolinium-DTPA of the RCA 8 days after PCI revealed a signal void along …
