Clinical Inclusion Criteria:
- Age 18 to 80
- Patients with chronic stable coronary artery disease, or unstable angina, or NSTEMI (Grace score<140), or STEMI more than one week
- Subjects suitable for PCI
- Subjects understand the trial purpose, volunteer to participate and sign informed consent form
Angiographic Inclusion Criteria (by visual):
- One coronary de novo bifurcation lesion (including Medina classification: 1,1,1 / 1,0,1 / 0,1,1, which need to be treated for both main and side branches)
- The reference vessel diameter of main branch is between 2.5 to 4.0 mm, length ≤ 30 mm. Before lesion preparation, lesion diameter stenosis shall be ≥70%, or ≥50% with evidence of myocardial ischemia
- The reference vessel diameter of side branch is ≥2.0 mm, length <20 mm. Before lesion preparation, lesion diameter stenosis shall be ≥70%
- No more than 3 lesions on the non-target vessel in the same operation, and shall be successfully treated before the target vessel
- No more than 1 non-target lesion on the target vessel in the same operation, and shall be successfully prepared before the target lesion (successful preparation of non-target lesion is defined as residual stenosis ≤30% and TIMI flow 3). After randomization, the non-target lesion shall be treated according to the assigned group, for the experimental group, using the experimental DCB is recommended; for the control group, using DES is recommended; Independent lesion on the same coronary artery is defined as interval >5 mm
- The target lesions of main and side branches must be successfully prepared (successful preparation is defined as: residual stenosis ≤30% , without NHLBI type C or above dissection, and TIMI flow 3)
Clinical Exclusion Criteria:
- Severe heart failure (NYHA IV), cardiogenic shock or severe valvular heart disease
- Left ventricular ejection fraction ≤35%
- Severe renal insufficiency (eGFR <30 ml/min)
- Severe liver insufficiency (glutamate transaminase (ALT) or glutamate transaminase (AST) >3 times the upper limit of normal)
- Pregnant women or planned pregnancy
- With a known allergy to heparin, contrast agent, paclitaxel and everolimus
- Unable to receive antiplatelet agents and anticoagulants, bleeding tendency or coagulopathy
- Life expectancy does not exceed 1 year
- Participating in other drug or device clinical trials without reaching the primary endpoint
- Subjects who had undergone coronary revascularization in the last 6 months
- Subjects not eligible by the investigator for other reasons
Angiographic Exclusion Criteria (by visual):
- In-stent restenosis lesion
- Left main bifurcation lesion
- Chronic total occlusive lesion
- Target vessel is severely distorted, angulated or calcified, which is anticipated difficult to cross for balloon or stent
- Target lesion remains significant residual thrombus after preparation
