1. Adjunctive oral anticoagulation treatment planned to continue after PCI
2. Age ≥ 75 years old
3. Baseline Hgb <11 g/dl (or anemia requiring transfusion during the 4 weeks prior to the index procedure)
4. Any prior intracerebral bleed
5. Any stroke in the last 12 months
6. Hospital admission for bleeding during the prior 12 months
7. Non skin cancer diagnosed or treated < 3 years, with a perceived increased risk for bleeding
8. Planned daily Nonsteroidal anti-inflammatory drugs (NSAID) (other than aspirin) or steroids for >30 days after PCI
9. Planned surgery that would require interruption of DAPT (within next 6 months)
10. Renal failure defined as: Creatinine clearance <40 ml/min
11. Thrombocytopenia (PLT <100,000/mm3)
12. Severe chronic liver disease defined as: patients who have developed any of the following: variceal hemorrhage, ascites, hepatic encephalopathy or jaundice
13. Expected non-compliance to prolonged DAPT for other medical reasons

Exclusion Criteria:

1. Pregnant and breastfeeding women

4. Procedure planned to require non-study stents, or stand-alone plain old balloon angioplasty (POBA) or stand-alone atherectomy
5. Active bleeding at the time of inclusion
6. Reference vessel diameter <2.25 - >4.0mm
7. Cardiogenic shock
8. Compliance with long-term single anti-platelet therapy unlikely
9. A known hypersensitivity or contraindication to aspirin, clopidogrel (or prasugrel, or ticagrelor if applicable), stainless steel, zinc, Biolimus A9™ or a sensitivity to contrast media, which cannot be adequately pre-medicated
10. PCI during the previous 12 months for a lesion other than the target lesion of the index procedure
11. Participation in another clinical trial (12 months after index procedure)
12. Patients with a life expectancy of < 12 months
13. Patients under judicial protection, tutorship or curatorship (for France only)
