Fully Bioresorbable Vascular Scaffolds (BVS) have been introduced with the objective to preserve native vessel geometry, allow for adaptive vessel remodeling with late lumen gain, restore physiological vasomotion, and avoid late adverse events including restenosis and scaffold thrombosis. 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.
The 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).

| OCT-guided PCI | Other | Patients assigned to the OCT-guided PCI strategy will undergo OCT prior to PCI to determine vessel and lesion dimensions and treatment strategy. OCT will be repeated at the end of the procedure and corrective PCI will aim to optimize the PCI result according to pre-specified criteria in terms of minimal lumen area, scaffold expansion, apposition, residual dissections or intra-scaffold thrombus formation |
| Measure | Description | Time Frame |
|---|---|---|
| Minimal in-scaffold lumen area (mm2) as assessed by OCT | The lumen area is assessed by OCT | 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Number of adverse events | Adverse events are defined as scaffold underexpansions, significant strut malappositions or uncovered struts, expansion asymmetries, any intrascaffold tissue, edge dissections, or restenoses (as assessed by OCT) | 6 months |
