This study aimed to identify whether clinical outcomes according to treatment strategy differed between left main (LM) and non-LM bifurcation lesions in the second-generation drug-eluting stent era.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods:<\/jats:title>\n            <jats:p>The Coronary Bifurcation Stenting registry III is a retrospective multicenter registry of 2648 patients with bifurcation lesions who underwent percutaneous coronary intervention with second-generation drug-eluting stent.
