Coronary Artery Disease
About this trial
This is an interventional treatment trial for Coronary Artery Disease
Eligibility Criteria
Inclusion Criteria:
- Patients ≥ 19 years old
- Patients with ischemic heart disease who are considered for coronary revascularization with PCI
- Significant coronary de novo lesion (stenosis > 70% by quantitative angiographic analysis) treated by single BVS ≤ 25mm
- Reference vessel diameter of 2.5 to 3.5 mm by operator assessment
Exclusion Criteria:
- Myocardial infarction
- Complex lesion morphologies such as aorta-ostial, unprotected left main, chronic total occlusion, graft, thrombosis, and restenosis
- 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

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.

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.
