Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients between 18-90 years of age.
  • Patients who gave written informed consent for participation in the trial.
  • Lesions are eligible for percutaneous coronary intervention (PCI).
  • Patient has stable/unstable angina or myocardial infarction (MI): all-comers.
  • ULMb (Medina 1,1,1) with/without left main ostial/shaft lesions. Downstream lesions in LAD or LCX could be covered by two stents. Severe calcification needing rotational atherectomy, orbital atherectomy or Laser are included.
  • Diameter stenosis in LAD/LM and LCX ≥ 50% by visual estimation or minimal luminal area by IVUS in LM ≤6 mm2.

You may not qualify if:

  • Restenotic lesions.
  • Patient was allergic to the study stent or protocol-required concomitant medications.
  • Patient is intolerable to dual anti-platelet therapy.
  • Patient has any other serious medical illness that may reduce life expectancy to \<12 months.
  • Patient is a woman who is pregnant or nursing.
  • Patient has a planned procedure that may cause non-compliance with the protocol or confound data interpretation.
  • Patient is participating in another clinical trial.
  • Patients in shock.
