A 61-year-old woman presented with chest pain while walking. The patient showed positive electrocardiographic findings for ischemia and slightly elevated troponin-I (0.271 ng/ml), suggesting acute coronary syndrome. Optical coherence tomography (OCT) confirmed a honeycomb-like structure with multiple signal-free channels (Fig. 1). A drug-eluting stent (DES) (everolimus-eluting stent: 2.5 × 15 mm) was then deployed because of atherosclerosis at the distal culprit lesion. OCT after stent deployment demonstrated thrombi protrusion and the complete resolution over 6 months (Fig. 2). A spontaneous recanalization of thrombi, forming a honeycomb-like structure, is rare in patients undergoing coronary angiography (1). The primary concerns are stent thrombosis because of malposition after DES stenting on the thrombi lesion, and in-stent restenosis of the atherosclerotic plaque with bare-metal stent implantation. Follow-up OCT at 6 months confirmed the successful DES deployment and its efficacy in acute coronary syndrome.
