Brief Summary:
The introduction of drug-eluting stents (DES) in the treatment of coronary artery disease has led to a significant reduction in morbidity. However, the first generation of these devices had no positive impact on the mortality after PCI (compared to bare metal stents), which was greatly attributed to a somewhat increased incidence of late and very late stent thrombosis. Concerns about the role of durable polymers as a potential trigger of inflammation and finally adverse events also led to the development of DES with biodegradable coatings, which leave after degradation of the coating only a bare metal stent in the vessel wall that does not induce an inflammatory response. While such biodegradable polymer DES are increasingly used in clinical practice, there is no data available from head-to-head comparisons between biodegradable and contemporary third generation durable polymer DES.

Primary Outcome Measures :
  1. Target vessel failure (TVF) [ Time Frame: 1 year ]
    Target vessel failure is a combined endpoint of cardiac death, target vessel related myocardial infarction and clinically driven target vessel revascularization.

Secondary Outcome Measures :
  1. Target lesion failure (TLF) [ Time Frame: 1 year ]
    Target lesion failure is a combined endpoint of cardiac death, target vessel related myocardial infarction, and clinically driven target lesion revascularization

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Minimum age of 18 years.
  • Significant coronary artery disease and lesion(s) eligible for treatment with drug eluting stents according to clinical guidelines and/or the operators' judgement.
