Comparison of PROVISIONal 1-stent Strategy with DEB Versus Planned 2-stent Strategy in Coronary Bifurcation Lesions.

\[The Purpose of the Clinical Study\] The purpose of this randomized comparison study is to compare the 1-stent strategy with a drug-eluting balloon and the 2-stent strategy in patients with non-LM coronary true-bifurcation lesions. \[Hypothesis\] In this study, the researchers intend to verify the hypothesis that the 1-stent strategy with a drug-eluting balloon is non-inferior to the 2-stent strategy in terms of target lesion failures (cardiac death, target vessel MI, or target vessel revascularization).
