In clinical practice, management of coronary osteal stenoses (aorto-ostial or bifurcation lesions) with percutaneous coronary intervention (PCI) might be associated with adverse outcomes largely due to a variety of procedural and long-term factors including inadvertent stent positioning (resulting in proximal or distal geographic miss), stent underexpansion along with potential stent thrombosis and restenosis, etc. 1-3 In this context, unfavorable outcomes of coronary stenting at these specific sites have been attributed to histopathological, anatomi cal as well as rheological factors. 2,3 Therefore, alternative techniques other than coronary stenting seem to be necessary for the management of coronary osteal stenoses. 2 In their recently published article, Erdoğan et al 1 have reported the effi cacy and safety of drug-coated balloons (DCBs) in the setting of left main stem (LMS) bifurcation stenoses (Medina types 0,1,0 and 0,0,1). In this context, we would like to comment on further implications of their study findings, and obtain further information on a couple of specific points:
