Figure 7. OCT findings (A-F) in the same patient as in Figure 6, after treatment of the ISR with repeat DES implantation.

The location of the cross-section images (A-E, top) is illustrated in the longitudinal display (F, bottom). A) Distal untreated segment of the previous stent. B-E) Treated segment (yellow arrow) demonstrating the 2 stent layers. There is also a significant protrusion of soft irregular material into the coronary lumen. (* denotes wire artefact). DES: drug-eluting stent; ISR: in-stent restenosis; LAD: left anterior descending coronary artery; LCX: left circumflex coronary artery; LM: left main; OCT: optical coherence tomography
