The European Bifurcation club (EBC) defines a coronary bifurcation lesion as a “coronary artery narrowing occurring adjacent to, and/or involving, the origin of a significant side branch (SB)”. A significant SB is a “branch that one does not want to lose in the global context of a particular patient” (1). There are several methods of classification; however, the medina classification (Figure 1) is widely accepted with a ‘true bifurcation’ lesion defined as Medina class (1,0,1), (1,1,1), or (0,1,1) (2).
