Patients and methods: The series is constituted by 420 patients with bifurcations lesions that will be treated with drug-eluting stents; 210 patients will be treated with side branch pre-dilation before main vessels stent implantation, while the remaining 210 patients will be randomized to no pre-dilation of the side-branch.\n\nPrimary end point:\n\n* TIMI flow at Side Branch after main vessel stent implantation.\n\nSecondary end points:\n\n* Time of re-wiring.\n* Number of used wires.\n* % of stenosis at Side Branch.\n* Levels of CK and TpI after the procedure.\n* Related cardiac events at 9 months. Relevance: Currently there has been controversy over the use of the side branch pre-dilation in patients with bifurcations lesions treated with provisional T-stenting.
