Not very impressive technique sir. Your guide is not coaxial. Burr coming out that way can dissect your LM. Also you start burr at the lesion. Too fast of movements rather than nice pecking. Stent is under expanded. Also stenting the ostium, good idea to protect the circ.
During rotational the guide was well enganged, the rota was done before the lesion with a standard speed for rota, post dilation was well performed. And I think no need to protect the LCX
