Brief Summary:
The German-Austrian ABSORB Register shall provide an analysis of acute and long-term safety as well as therapy outcomes of the ABSORB (trade mark) bioresorbable vascular scaffold system in patients suffering from coronary artery disease.

Condition or disease Intervention/treatment
Coronary Artery Stenosis Device: ABSORB Scaffold

Detailed Description:

The register collects prospective data regarding the quality of care of this therapy concept including specifically the following objectives:

  • Documentation of all consecutive patients having been treated with the ABSORB biore-sorbable vascular scaffold system under clinical real-world conditions
  • Documentation of indications, procedural results, and short and long-term outcomes
  • Documentation of the technical performance of ABSORB implant procedures
  • Collection of safety data, in particular documentation of hospital mortality, major non-fatal complications (especially myocardial infarction, Re-PCI (percutaneous coronary intervention) or CABG (coronary artery bypass grafting), stroke, thrombosis)
  • Documentation of long-term patient safety marked by mortality and major non-fatal complications (especially myocardial infarction, Re-PCI or CABG, stroke, thrombosis) at 30 days, 6 months, 2 years and 5 years
  • Gathering of health economics data (capture of direct costs, especially with view to change of medication and outpatient/inpatient hospital services, and indirect costs) pre and post ABSORB implant
  • Gathering data on the quality of life pre and post ABSORB implant to document individual QoL dimensions as well as QALY (quality adjusted life year) data

Drug Information available for: Everolimus

Group/Cohort Intervention/treatment
Implantation of ABSORB Scaffold
Patients suffering from coronary artery stenosis with an indication for implantation of ABSORB scaffold
Device: ABSORB Scaffold
Implantation of a drug-eluting vascular scaffold, which is completely resorbable to improve the blood flow in coronary arteries in the presence of stenosis
Other Name: ABSORBTM Everolimus-eluting Bioresorbable Vascular Scaffold

Primary Outcome Measures :
  1. Number of serious adverse cardiac events [ Time Frame: 5 years after index procedure ]

    The following events will be evaluated:

    • Death
    • Myocardial infarction
    • Clinically motivated target vessel revascularization
    • Clinically motivated target lesion revascularization
    • Composite target parameter of the aforementioned events (MACE, major adverse cardiac event) as the primary target parameter
    • Stroke
    • Composite target parameter of the aforementioned events including stroke as the primary target parameter (MACCE, major adverse cardiac and cerebrovascular event)
    • Stent thrombosis

Secondary Outcome Measures :
  1. Success of ABSORB implantation [ Time Frame: during implantation of ABSORB scaffold ]

    The following parameters will be evaluated to assess procedural outcome:

    • Technical success: If the residual stenosis is less than 30% in the ABSORB covered lesion segment at the end of the procedure based on visual estimation
    • Therapy success: Technical success and no periprocedural complications
    • Clinical success: Therapy success and no serious adverse cardiac (and cerebrovascular) events (MACE, MACCE)
    • TIMI (thrombolysis in myocardial infarction) flow pre and post implant
    • Sudden occlusion of side branch in the case of bifurcation stenosis
    • Optional: Quantitative coronary angiography (QCA) with index treatment: final in-scaffold and in-segment percentage diameter stenosis (%DS), reference vessel diameter

Other Outcome Measures:
  1. Effectiveness of ABSORB implantation [ Time Frame: 5 years follow-up period ]

    Effectiveness of ABSORB implantation will be assessed based on the following parameters:

    • Target vessel failure (TVF): This includes cardiac death, target vessel myocardial infarction (Q-wave or non-Q-wave MI) or clinically motivated target vessel revascularization (TVR), percutaneous or surgical.
    • Target lesion failure (TLF): This includes cardiac death, target vessel myocardial infarction (Q-wave or non-Q-wave MI) or clinically motivated target lesion revascularization (TLR), percutaneous or surgical.

  2. Change in quality of life [ Time Frame: 5 years follow-up period ]

    Changes in quality of life will be assessed by measuring

    • Angina pectoris scores (incl. CCS score, Canadian Cardiovascular Society score) and heart failure scores (NYHA, New York Heart Association score)
    • Standardized questionnaire for quality of life (EQ-5D)
    • Standardized questionnaire for health-related quality of life of patients with coronary artery disease (Seattle Angina Questionnaire, SAQ)

  3. Health-economical effects of ABSORB scaffold implantation [ Time Frame: 5 years follow-up period ]

    Health-economical effects will be assessed by measuring

    • Direct costs: medication, visits to general practitioners and specialists, hospitalizations, inpatient and outpatient rehab, patient care services
    • Indirect costs: disability, reduced earning capacity
