Inclusion criteria

Inclusion criteria: Bifurcation lesions with a side branch of 2.0 mm that can be identified by CAG Bifurcation lesions that can be treated by provisional side branch stenting No remote lesions in the same vessel with the target lesion New lesions or restenotic lesions without a stent implanted Lesions in which stenting is feasible; the visually estimated reference diameter of the main vessel is over 2.5 mm; if two or more bifurcation lesions are found in the reference lesion, the proximal lesion will be studied.
