75 consecutive patients with bifurcated lesions undergoing PCI with the provisional TAP-stenting technique with ZES implantation will be enrolled. Procedural details, post-PCI cardiac enzyme release, clinical outcome up to 1 year will be prospectively recorded. After the procedure, the subgroup of patients in which complete revascularization has been achieved (no untreated stenosis >50% in any other vessel, no residual stenosis >50% in any other treated vessel), will enter a systematic assessment of inducible ischemia by early (<8 days) and late (6-month) exercise tests.
