title: B2 lesions are true bifurcation lesions simply categorized as one group according to the Movahed bifurcation classification.
abstract: Ito et al reported low adverse events in true bifurcation lesions treated with rotational atherectomy in a recent issue of the Journal of Invasive Cardiology. However, their definition of true bifurcation lesions is not correct. They defined only Medina 1,1,1 as a true bifurcation lesion. However, true bifurcation lesions are Medina 1,1,1, 1,0,1 and 0,1,1 lesions, which are all summarized as B2 lesions when using the Movahed classification. This letter discusses this important issue.
