Figure 1. Angiography and optical coherence tomography findings. A) Angiography showed in-stent restenosis in the right coronary artery. B) External elastic membrane diameter at the distal reference was 5.14 mm. C) - E) Recanalised thrombus with multiple channels within the stent. D) Recanalised thrombus with malapposition (white arrows) and uncovered struts (yellow arrow). F) Neoatherosclerosis with lipid pool (asterisk) and microvessels (white arrow) in the setting of an undersized stent.

A 68-year-old man was admitted to our hospital with unstable angina. His medical history was remarkable for an acute myocardial infarction one year before, treated with a zotarolimus-eluting stent (3.5×30 ...
