Masking description
All imaging analyses will be performed at an independent core laboratory (Cardiovascular Department, San Giovanni Addolorata Hospital, Rome, Italy) by experienced operators blinded to procedural data and clinical outcomes.
Eligibility
Inclusion criteria
Presence of complex coronary lesions defined as follows: * long lesions (\>28 mm); * CTO, a total occlusion of duration more than 3-months; * Lesions involving a bifurcation, defined as a division with a side branch large enough to be stented (i.e. \>2.25 mm); * Patients requiring 4 or more stents * Reference vessel diameter: \>2.25 mm to \<4.0 mm
Exclusion criteria
* Age under 18 years old; * Significant co-morbidity precluding clinical follow-up; * A positive pregnancy test in women with child-bearing potential; * Contra-indication to dual anti-platelet therapy; * Thrombocytopenia \<100,000/uL; * Major surgery planned which will lead to discontinuation of antiplatelet therapy; * In-stent restenosis; * Treatment of saphenous vein graft; * CTO with long sub-intimal tracking (\> 20 mm).
