SPAGO: Sirolimus Paclitaxel Angiographic Gain Objective

Inclusion Criteria: 1. Male or female subjects ≥18 years 2. Subject with chronic stable angina or stabilized acute coronary syndromes with normal cardiac biomarker values. 3. The subject has at least one de-novo lesion in a small vessel (\>2.00 mm and ≤3.00 mm prior to pre-dilatation) with a diameter stenosis between 50% and 99% (prior to pre-dilatation). It is possible to enroll subjects that have a stent previously implanted in the same epicardial territory (main vessel and ramifications) of the target lesion 4. Patients with target lesion to be treated with DCB \< 30 mm in length (up to 40 patients) or with DCB ≥ 30 mm in length (at least 100 patients) 5. Able to understand and provide informed consent and comply with all study procedures including 12 months angiographic follow-up 6. Subject must have completed the follow-up phase of any previous study Exclusion Criteria: 1. Subject is a woman who is pregnant or nursing (a pregnancy test must be performed within 7 days prior to the index procedure in women of child-bearing potential) 2. Evidence of ongoing acute myocardial infarction (AMI) in ECG and/or elevated cardiac biomarkers (according to local standard hospital practice) have not returned within normal limits at the time of procedure 3. Known contraindication or hypersensitivity to sirolimus, paclitaxel, or to medications such as aspirin, heparin, and all of the following four medications: clopidogrel bisulfate, ticlopidine, prasugrel, ticagrelor 4. Subjects who experienced a previous PCI with DCB in the epicardial territory (main vessel and ramifications) where the target lesion is located, during the last 12 months 5. Subject suffered from stroke/TIA during the last 6 months 6. LVEF \<30% 7. Platelet count \<100,000 cells/mm3 or \>400,000 cells/mm3, a WBC of \<3,000 cells/mm3, or documented or suspected liver disease (including laboratory evidence of hepatitis) 8. Known renal insufficiency (e.g. serum creatinine \>2,5 mg/dL, creatinine clearance ≤30 mL/min or eGFR ≤30 mL/min/m2), or subject on dialysis, or acute kidney failure (as per physician judgment) 9. Subject undergoing planned surgery within 1 month with the necessity to stop DAPT 10. History of bleeding diathesis or coagulopathy 11. The subject is a recipient of a heart transplant 12. Concurrent medical condition with a life expectancy of less than 12 months 13. The subject is unwilling/not able to return for angiographic re-catheterisation at 12 months follow-up 14. Currently participating in another trial Angiographic exclusion criteria: 15. Target vessel size \>3.00 mm 16. Target vessel size ≤2.00 mm 17. Target lesion has a diameter stenosis \< 50% prior to pre-dilatation 18. Target lesion has a total occlusion or TIMI flow \< 2 prior to pre-dilatation 19. Pre-dilatation of the target lesion not performed or not successful (residual stenosis \> 30%, TIMI flow \< 3 and presence of major angiographic dissections) 20. Target lesion in left main stem 21. The target vessel contains visible thrombus 22. Aorto-ostial target lesion (within 3 mm of the aorta junction) 23. Lesion is located within an arterial or saphenous vein graft or distal to a diseased arterial or saphenous vein graft
