Periprocedural stent thrombosis after percutaneous coronary intervention for a bifurcation lipid-rich plaque

Figure 1. Stent thrombosis due to atheromatous protrusion after stenting. Left: cross-sectional OCT images (A1-D1; *=calcification) at four stages. Right: corresponding coronary angiographies (A2-D2; black arrows=LAD; white arrows=diagonal branch) and longitudinal OCT views of LAD (A3-D3; red vertical bars indicate site of stent thrombosis and correspond to site of OCT cross-sections; white arrows=diagonal branch). A1-A3. Pre-interventional OCT/angiography: circumferential, predominantly lipid-rich plaque (A1). B1-B3. OCT/angiography of stent thrombosis (arrow in B2): OCT (B1) shows thrombus (red arrow) attached to atheromatous protrusion (yellow arrow), blue arrows=buried stent struts. C1-C3. OCT/...
