Eligibility Criteria

Inclusion

  • Related to the patients:
  • Age ≥18 years old
  • Patients who agree to accept the angiography follow-up visit at 9-month and follow up visits at 1-month, 6-month, 9-month, 1-year, 2-year, 3-year, 4-year and 5-year
  • Patients with stable angina, unstable angina, old myocardial infarction or proven asymptomatic ischemia
  • Patients who can receive any kind of coronary revascularization (including balloon angioplasty, stent implantation or coronary artery bypass grafting)
  • Related to lesion:
  • Restenosis after the first stent implant (including bare metal stents, stents with inert coating, and stents with active coating): Type Mehran I, Type II and Type III; the reference blood vessel diameter is 2.5 mm-4.0 mm, length ≤ 26mm
  • Before surgery, stenosis diameter must be ≥ 70% or ≥ 50% and accompanied by ischemia
  • The distance between other lesion requires interventional therapy and the target lesion must be \> 10mm
  • One subject is allowed to have 2 target lesions at most, and 1 paclitaxel drug balloon for each lesion for dilation
  • Residual stenosis must be ≤ 30% after pre-dilatation, and dissection must be ≤ NHLBI type B

  • Pregnant or lactating women, or women who plan to get pregnant within 12 months or refuse to take effective contraceptives
  • Patients with cardiogenic shock
  • The patients had cerebral stroke within 6 months before being included, or have a history of peptic ulcer or gastrointestinal bleeding, or the patients have a bleeding tendency according to the investigator. Patients who are forbidden to use anticoagulation agents or anti-platelet drugs, and unable to tolerate aspirin or clopidogrel. Patients who are not able to tolerate and comply with dual antiplatelet therapy for at least 3 months after operation
  • Patients who have Myocardial Infarction with thrombus or coronary slow flow symptoms and require immediate intervention
  • Patients who had ST-Elevation Myocardial Infarction within 1 week before being included
  • Patients with severe congestive heart failure or NYHA grade IV heart failure
  • Patients with moderate or severe valvular heart disease
  • Patients who had heart transplantation

  • The patients are participating in any other clinical trials before reaching the primary endpoints
  • Patients who are unsuitable for the study according to the investigator due to other reasons
  • Related to the Lesion:
  • Patients with total occlusion at the target lesion
  • Lesion which cannot be treated by percutaneous transluminal coronary angioplasty (PTCA) or percutaneous intervention (PCI)
  • Reference vessel diameter \< 2.0mm
  • Patients with multiple lesions (≥ 3) requiring percutaneous coronary intervention treatment in the same artery
  • 3-vessel disease that all need to be intervened
  • The diameter of the branch lesions in the target lesion ≥ 2.5mm
  • LM lesions and Ostial lesion within 5mm to the root aorta
  • Non-target lesion was not intervened successfully before target lesions being intervened
  • Related to concomitant therapy:
  • Patients cannot tolerate aspirin and/or clopidogrel and or tricagrelor, patients with the history of neutrocytopenia or thrombocytopenia, or patients with severe hypohepatia and prohibited to take clopidogrel
  • Patients known allergic to paclitaxel
  • Patients known allergic to contrast materials
