- Reference vessel diameter <2.5 mm or >3.5 mm
- Heavy calcified lesions (definite calcified lesions on angiogram)
- Lesions requiring 2 or more BVS
- Contraindication or hypersensitivity to anti-platelet agents or contrast media
- Treated with any metallic stent or BVS within 3 months at other vessel
- Creatinine level ≥ 2.0 mg/dL or ESRD
- Severe hepatic dysfunction (3 times normal reference values)
- Pregnant women or women with potential childbearing
- Inability to follow the patient over the period of 1 year after enrollment, as assessed by the investigator
- Inability to understand or read the informed content

Aktiv komparator: Angiography-guidance
Everolimus-eluting bioresorbable vascular scaffold (Absorb, Abbott Vascular, Santa Clara, CA, USA) was made from a bioabsorbable polylactic acid backbone which is coated with a more rapidly absorbed polylactic acid layer that contains and controls the release of the antiproliferative drug, everolimus.
PCI will be performed with BVS under conventional coronary angiography without any other intravascular imaging modality.

Experimentell: OCT-guidance
Everolimus-eluting bioresorbable vascular scaffold (Absorb, Abbott Vascular, Santa Clara, CA, USA) was made from a bioabsorbable polylactic acid backbone which is coated with a more rapidly absorbed polylactic acid layer that contains and controls the release of the antiproliferative drug, everolimus.
For optimized PCI, both conventional coronary angiography and optical coherence tomography can be used before and after stent implantation.
OCT study should be checked at the final post-procedure and stent implantation is optimized.

Major cardiac and cerebrovascular adverse events (MACCEs)
Tidsram: until one year
|
Cardiac death, myocardial infarction, target vessel revascularization, stent thrombosis, cerebrovascular accident and major bleeding between OCT guidance vs. angiography-only guidance PCI until 12 months *Major bleeding ; causing mortality, hypovolemic shock or severe hypotension requiring inotropes or surgery, intrapericardial with tamponade, significant disabling (e.g. intraocular bleeding leading to loss of vision), symptomatic intracranial haemorrhage, intraocular bleeding leading to loss of vision, hemoglobin drop ≥ 3g/dL, or requiring transfusion more than 2 units |

Percentage of incomplete scaffold struts apposition
Tidsram: six months after stent implantation
|
Scaffold strut malapposition: Malapposition is defined by a clear seperation between the abluminal side of the strut and the vessel wall.
As a result, scaffold malapposition is defined as the presence of any malapposed struts.
percentage of malapposed struts (% malapposed strut) was the ratio of malapposed struts from total analyzable struts.
