In study-1, the purpose of this study is to compare the long-term outcome of provisional stenting between EES and SES deployment. In study-2, it is to prove the following hypothesis " Asymmetrical expansion in the bifurcation lesion leads to frequent inhomogeneous intimal growth on the strut and thrombus attachment."
Kissing balloon inflation brings asymmetrical expansion which may lead to a risk of disturbance of endothelialization. We will investigate the following issues. 1. Impact of asymmetric expansion induced by kissing balloon technique on mid and long term results 2. Difference between SES and EES 3. Impact of abnormal OCT findings on long-term clinical outcome (3yr)

RECRUITINGMajor adverse cardiac events
Cardiac death, myocardila infarction, target lesion revascularization, target vessel revascularization, and stent thrombosis are monitored.
Time frame: 3 years
abnormal intimal coverage
Optical coherence tomography (OCT) is planned at the 9-month follow-up period. Unevenness of intimal growth, number of uncovered struts, and frequency of thrombus attachment are evaluated.
Time frame: 9 months
