Objectives

Narrative objectives1

Primary objective: To determine the predictive ability of plaque characteristics assessed by optical coherence tomography (OCT) in the non-target vessel with luminal irregularity (study imaging vessel) on luminal narrowing during 12 months. Plaque characteristics will be assessed, as potential predictors, manually by experienced assessors using validated software (QCU-CMS, LKEB, Leiden University, Leiden, Netherlands) and automatically using deep learning methods.
Secondary objective: To assess clinical impact of baseline and/or 12-month changes of OCT features on clinical cardiovascular adverse events during the long-term follow-up.

Assessment

Primary outcomes

Changes in lumen area in the non-significant stenosis (%DS 30%-90%) assessed by OCT from baseline to 12-month follow-up.
Matching will be done using anatomical landmarks such as side branches and ostium of the coronary arteries.
Following OCT parameters will be assessed in paired frames between baseline and follow-up.
- Luminal area
- Fibrous cap thickness
- Lipid arc, lipid length
- Calcification arc, calcification length)

Key secondary outcomes

Secondary clinical endpoints
Any death, cardiac death, non-fatal myocardial infarction, and any ischemia-driven coronary artery revascularization.
Secondary safety endpoints
Amount of contrast used, cumulative radiation dose, intervention time, and any OCT procedure related adverse events.
Secondary CT endpoints
Changes in lumen volume in the non-culprit vessels assessed by computed tomography from baseline to 36-month follow-up.

Key inclusion criteria

1. Patients who is 20 years of age or older at informed consent
2. Patients who submit signed consent by themselves or their legally acceptable representative
3. Elective or ad hoc PCI in patients with stable angina, acute coronary syndrome, or silent myocardial ischemia for target lesions in the native coronary artery. Target lesions fulfill at least one of the following criteria: 1) visually estimated %diameter stenosis >=90%, 2) fractional flow reserve <0.80, instantaneous wave-free ratio <0.89 or 3) presence of myocardial ischemia assessed by non-invasive test such as scintigraphy, stress echocardiography, and stress electrocardiography.
4. Patients who had at least one non-target coronary artery in which 1) no previously treated lesions and 2) non-severe stenosis (30% < visually estimated %DS < 90%) in the non-target vessel or >5mm apart from the culprit lesions. Except for contraindication, physicians are encouraged to confirm the stenosis is not significant by fractional flow reserve test (i.e. FFR>=0.80), instantanoues wave-free ratio (i.e. iFR>=0.89) or non-invasive test.

Key exclusion criteria

1. Subject with left main lesion.
2. Subject with a history of coronary artery bypass grafting.
3. Known renal insufficiency (estimated serum creatinine clearance <30ml/min or maintenance hemodialysis).
4. Severe angulation (>90 degrees) or excessive tortuosity (>two 45 degrees angles) not suitable for OCT assessments.
5. Female of childbearing potential (age <50 years and last menstruation within the last 12 months), who did not undergo tubal ligation, ovariectomy or hysterectomy
6. Life expectancy less than 1 year.
7. Known allergy against protocol-required medications including aspirin, prasugrel, clopidogrel, heparin, iodinated contrast (the latter in case it cannot be adequately premedicated).
8. Cardiogenic shock or decompensate heart failure requiring intubation, vasopressors, and hemodynamic support (IABP and/or PCPS).
9. History of bleeding diathesis or known coagulopathy.
10. Planned surgery within the next 12 months
