Clopidogrel was discontinued after 12 months; aspirin was maintained indefinitely. Coronary angiography proved definite stent thrombosis (ST). After manual thrombus aspiration restenosis involving both stents was observed (Figure 1A). Optical coherence tomography (OCT) detected in-stent heterogeneous, low-intensity and attenuated neointima (Figure 1B, Figure 1C, Figure 1F, Figure 1G, Moving image 1, Moving image 2) compared with the homogeneous, high-intensity signal of adjacent fibrous tissue (Figure 1D, ...
