Figure 3. The SB/aSB wire is jailed intraluminally in the (crushed) proximal segment of the pMV stent. See main text for detailed description.

The green image border denotes the optimal step. The red arrows and image borders denote where potential mistakes may occur (pitfalls). The violet arrows and image borders denote the corrective steps that arise from the pitfalls. The light blue arrows and image borders denote the steps commonly performed not suspecting the previous pitfalls. 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
