Figure 1. OFDI showing a honeycomb-like structure with multiple intraluminal microchannels confirming the presence of recanalised thrombus. Upper panel: longitudinal view of the right coronary artery. The dashed white lines denote the cross-sectional locations for A, B and C. A), B) & C) Three locations with clear recanalisation in organised thrombus. From left to right: conventional OFDI intensity, birefringence, magnified birefringence (* denotes zones of high birefringence surrounding microchannels).

A 69-year-old female patient was admitted to our institution for potential treatment of a non-ST-segment elevation myocardial infarction after eight days of intermittent pain. Angiography showed an unusual filling defect in ...
