Abstract

An 84-year-old patient with prior coronary artery bypass surgery presented with non-ST segment elevation acute myocardial infarction. The culprit lesion was at the distal anastomosis of a saphenous vein graft (SVG) to the right posterior descending artery. The proximal right coronary artery was chronically occluded. Because of significant disease both proximal and distal to the SVG anastomosis, percutaneous intervention of the SVG carried high risk for acute vessel closure. The native right coronary artery chronic total occlusion was successfully recanalized, enabling complete revascularization of the right coronary artery. The SVG was then occluded using an Amplatzer vascular plug.

Keywords: DK crush; chronic total occlusion; culprit vessel; non-ST segment myocardial infarction.
