The primary aim of this study is to compare the clinical efficacy and safety of OCT-guided(optical coherence tomography (OCT)-guided) and IVUS-guided(Intravascular ultrasound (IVUS)-guided) strategies in patients undergoing Percutaneous coronary intervention (PCI) with contemporary drug-eluting stents (DES) or drug-coated balloons (only for in-stent restenosis) for significant obstructive Coronary artery disease (CAD). The investigators hypothesize that OCT-guided PCI is non-inferior to IVUS-guided PCI with respect to primary end point of target-vessel failure (cardiac death, target-vessel myocardial infarction \[MI\], or ischemia-driven target-vessel revascularization \[TVR\]) at 1 year after randomization.

Rate of target vessel failure
A composite of cardiac death, target-vessel MI or ischemia-driven TVR) at 1 year after randomization. A composite endpoint is an endpoint that is a combination of multiple clinical endpoints. An event is considered to have occurred if any one of several different events is observed.
Time frame: 1 year
Rate of cardiac Death
Time frame: 1, and 5 years
Rate of target vessel myocardial infarction
Time frame: 1, and 5 years
Rate of ischemia-driven target vessel revascularization
Time frame: 1, and 5 years
Rate of death
cardiac, vascular, non-cardiovascular death
Time frame: 1, and 5 years
Rate of myocardial infarction
periprocedural or spontaneous, Q-wave or non-Q-wave.
Time frame: 1, and 5 years
Rate of stent thrombosis
Stent thrombosis is defined according to according to the definite or probable criteria of the Academic Research Consortium.
Time frame: 1, and 5 years
Rate of stroke
Stroke is defined as focal loss of neurologic function caused by an ischemic or hemorrhagic event, with residual symptoms lasting at least 24 hours or leading to death.
Time frame: 1, and 5 years
Rate of repeat revascularization
Any, target-lesion or non-target-lesion, target-vessel or non-target-vessel, ischemia-driven or non-ischemia-driven.
Time frame: 1, and 5 years
Rate of any hospitalization
Cardiac or non-cardiac causes.
Time frame: 1, and 5 years
Rate of bleeding events
Life-threatening or disabling, major bleeding, or minor. Bleeding events are assessed according to the Bleeding Academic Research Consortium (BARC) criteria.
Time frame: 1, and 5 years
Rate of target-lesion failure
Cardiac death, target-vessel myocardial infarction or ischemia-driven target-lesion revascularization
Time frame: 1, and 5 years
Rate of contrast-induced acute kidney injury
Contrast-induced nephropathy is defined as either a greater than 25% increase of serum creatinine or an absolute increase in serum creatinine of 0.5 mg/dl within 72 hours after PCI.
Time frame: 3 days
Rate of procedural complications requiring active intervention that were related to PCI or intracoronary imaging devices
Procedural complications (e.g., angiographic dissection of at least type B, coronary perforation, vasospasm, thrombus formation, air embolization, slow flow or no reflow, distal embolization, acute closure, ventricular arrhythmia, cardiac tamponade, or cardiogenic shock) requiring active interventions (prolonged balloon inflations, additional stenting required, thrombus aspiration, pericardiocentesis, cardioversion, or use of mechanical circulatory support devices), which are related to PCI procedures or intravascular imaging evaluation.
Time frame: 1 day
Rate of angiographic or imaging-based device success
Patient- or lesion-level analysis. Angiographic device success is defined as successful PCI at the intended target-lesion with final in-stent residual stenosis of less than 30% by quantitative coronary angiography (QCA). Imaging-based device success is defined as successful PCI at the intended target-lesion, which fulfills the optimal criterial for stent implantation by IVUS or OCT.
Time frame: 1 day
