European Heart Journal - Cardiovascular Imaging (2017) 0, 19,Take home message,Provisional side branch stenting should be the default approach SB rewiring site impacts on MV stent distortion after SB dilation. Crossing of the MV stent struts in the most distal cell is associated with better SB ostium scaffolding 3D-OCT enable us to verify recrossing wire position,Thanks,
