For the optimal treatment of the side branch (SB) after main vessel (MV) stenting in coronary bifurcation lesions, confirming the guide wire recrossing (GWR) point in the SB ostium is crucial.1 3-Dimensional imaging with optical coherence tomography (OCT) can visualize the GWR point clearly. We encountered unusual deflection of the protruded struts treated with proximal optimization technique (POT) and SB dilation, when the GWR into proximal cells of the struts overhung in the SB ostium. Deflection to the SB. A 67-year-old man with a 1-1-0 lesion…
