The aim of the study is to investigate the feasibility of Paclitaxel-eluting PTCA-balloon dilation (SeQuent Please) followed by bare metal stent (Coroflex ) deployment in the main branch (reference diameter: ≥ 2.5 mm and ≤ 3.8 mm, reference diameter of side branch: ≥ 2.0 mm and ≤ 3.5 mm, length of stenoses in either branch ≤ 20 mm) in the treatment of significant (>70%) de-novo-bifurcation stenoses of any Medina classification type in the native left coronary artery as reflected by procedural success and to evaluate the preservation of vessel patency.
