Thrombotic arch in ST-segment elevation myocardial infarction: Comparison between two-dimensional and three-dimensional optical frequency domain imaging

摘要

A 54-year-old female presented with inferoposterior ST-segment elevation myocardial infarction. Coronary angiogram revealed total occlusion of the proximal left circumflex artery. Following a thrombus aspiration, without administration of glycoprotein IIb/IIIa inhibitor, direct stenting with a drug-eluting metallic stent was performed. After stent implantation, angiogram showed thrombolysis in myocardial infarction (TIMI) grade III flow, without any evidence of intralum-inal defect within the culprit lesion (Panel A, red arrow). Subsequently, we performed the optical frequency domain imaging (OFDI; Terumo Europe N.V., Leuven, Belgium) with a pullback speed of 20 mm/s.
