Figure 5. The catheter stops inside the pMV stent at the level of the SB/aSB origin (after proximal rewiring, KBI and distal POT).

See main text for detailed description. The green arrow and image borders denote the optimal steps. The red arrows and image borders denote where potential mistakes may occur (pitfalls). The violet arrow and image border denote the corrective step that arises from the pitfall. The light blue arrows and image border denote the step commonly performed, not suspecting the previous pitfall. dMV: distal main vessel; IVUS: intravascular ultrasound; KBI: kissing balloon inflation; OCT: optical coherence tomography; pMV: proximal main vessel; POT: proximal optimisation technique; SB/aSB: side branch/assigned side branch
