KEYWORDS
coronary bifurcation lesion; drug-eluting stent; lesion complexity; major adverse cardiac event; stent thrombosis
OBJECTIVES - The present study established criteria to differentiate simple from complex bifurcation lesions and compared 1-year outcomes stratified by lesion complexity after provisional stenting (PS) and 2-stent techniques using drug-eluting stents.
