Study population: Patients with coronary bifurcation lesion treated with 2nd generation drug-eluting stents

Brief summary: The COBIS III registry is a multi-center, real-world registry of 2nd generation drug-eluting stenting in coronary bifurcation lesions in South Korea. From 21 major coronary intervention centers in Korea, a total of 3,000 patients (anticipated) will be enrolled in this database between January 2010 and December 2014.

The aim of the study was to investigate long-term clinical results and predictors of adverse outcomes after percutaneous coronary intervention with 2nd generation drug-eluting stents for coronary bifurcation lesions in South Korea.


Eligibility criteria: Inclusion Criteria:

* Age \>=19 years
* Any type of de novo bifurcation lesion in major epicardial artery: unprotected left main coronary bifurcation lesion, LAD - diagonal, LCX-OM, distal RCA bifurcation. (Excluding RCA-RV branch bifurcation, branch bifurcation)
* Side branch or LCX reference diameter \>= 2.3 mm and at least stentable with 2.5 mm stent
* Treated with drug-eluting stent during the period of 2010. 1 \~ 2014. 12

Exclusion Criteria:

* Protected left main disease previous CABG for LAD or LCX territory
* Cardiogenic Shock
* History of CPR in the same hospitalization
* Patients with severe left ventricular systolic dysfunction (ejection fraction \< 30%)
