Although randomized clinical trials in low risk patients to date suggest non-inferiority in terms of safety and efficacy compared with metallic DES, several reports have raised concerns regarding the scaffold thrombosis highlighting the importance of technical considerations regarding lesion preparation and scaffold expansion. OCT offers the opportunity to plan the procedure and optimize the implantation of BVS.\n\nThe hypothesis of the present study is that a strategy of OCT-guided PCI using BVS is superior to angiography-guided PCI (e.g. by selecting scaffold dimension on the basis of a pre-procedural OCT and applying corrective measures in case of suboptimal treatment result as indicated by OCT).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.

Angiographically significant (\\>50% visual estimation) stenosis present in at least one native coronary artery and evidence of ischemia.\n\nExclusion Criteria:\n\n1. Subjects with left main lesion.\n2. Aorto-ostial lesion location within 3 mm of the aorta junction (both right and left).\n3. Subjects with restenosis or stent thrombosis in the target vessel.\n4. Severely calcified lesions requiring rotablation.\n5. Bifurcation with sidebranch \\>2.5mm or any sidebranch that possibly requires treatment with angulation \\>70°\n6. Severe angulation (\\>90°) or excessive tortuosity (\\>two 45° angles)\n7. Known renal insufficiency (serum creatinine clearance \\<45ml/min or receiving dialysis).\n8.
