NCT01642992

Brief Summary

The COBIS II registry is a multi-center, real-world registry of drug-eluting stenting in coronary bifurcation lesions in South Korea. From 18 major coronary intervention centers in Korea, a total of 2,873 patients were enrolled in this database between January 2003 and December 2009. The aim of the study was to investigate long-term clinical results and predictors of adverse outcomes after percutaneous coronary intervention with drug-eluting stents for coronary bifurcation lesions in South Korea.
