ABSORB: Postmarketing Surveillance Registry to Monitor the Everolimus-eluting Bioresorbable Vascular Scaffold in Patients With Coronary Artery Disease (ASSURE)

The recommendation to implant BVS in an individual patient is purely based on clinical grounds. These are determined by the instructions for use (IFU) of the BVS and by the clinical experience accumulated so far from clinical studies.These studies suggest that the BVS should be implanted under certain conditions, which are determined by the patient and the coronary lesion treated:

Eligible:

Regarding to patient

• Patient ≥ 18 and ≤ 75 years with a live expectancy of at least 5 years with ischemic heart disease (chronic, NSTEMI and unstable angina) due to one or more de novo native coronary artery lesions
• Patients with evidence of myocardial ischemia

Regarding to lesion

• Reference vessel diameter ≥ 2.0 mm and ≤ 3.8 mm, visually estimated and by online QCA
• Percent diameter stenosis ≥ 50% and < 100%, visually estimated and by online QCA
• TIMI ≥1
• Previous interventions of target vessel lesions should have been done ≥ 6 months prior to index procedure and > 10 mm distal to the target lesion
• Previous interventions of non-target vessel lesions should have been done ≥ 30 days prior to index procedure
• In case of >1 target lesions, those should be from different epicardial vessels

Not eligible:

Regarding to patient

• Patient in whom antiplatelet therapy and/or anticoagulant therapy is contraindicated
• Patient with a known hypersensitivity or contraindication to aspirin, both heparin and bivalirudin, clopidogrel, ticlopidine, prasugrel and ticagrelor, everolimus, poly (L-lactide), poly (D,L-lactide), or platinum, or with contrast sensitivity, who cannot be adequately premedicated
• Patient has a known diagnosis of acute myocardial infarction (STEMI) within 72 hours preceding the index procedure and CK and CK-MB have not returned within normal limits at the time of procedure
• Patient is currently experiencing clinical symptoms consistent with STEMI
• Patient has current unstable arrhythmias
• Patient has a known left ventricular ejection fraction < 30%
• Patient has received a heart transplant or any other organ transplant or is waiting for any organ transplant
• Patient receiving or scheduled to receive chemotherapy for malignancy within 30 days prior to or after procedure
• Patient is receiving immunosuppression therapy and has known immunosuppressive or autoimmune disease
• Patient is receiving or scheduled to receive chronic anticoagulation therapy
• Elective surgery is planned within the first 6 month after the procedure that will require discontinuing either aspirin or clopidogrel
• Patient has a platelet count < 100 000 cells/mm3 or > 700 000 cells/mm3, a WBC of
• < 3000 cells/mm3, or documented or suspected liver disease
• Patient has known renal insufficiency
• Patient has a history of bleeding diathesis or coagulopathy or will refuse blood transfusions
• Patient has cerebrovascular accident or transient ischemic neurological attack within the past six month
• Patient has had a significant GI or urinary bleed within the past six months
• Patient has extensive peripheral vascular disease that precludes safe 6 French sheath insertion
• Patient has other medical illness (e.g., cancer or congestive heart failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non.compliance with the clinical study plan, confound the data interpretation or is associated with a limited life expectancy (i.e., les than one year)
• Women of childbearing potential who have not undergone surgical sterilization or are not post-menopausal

Regarding to lesion

• Aorto-ostial location
• Left main location
• Located within 2 mm of the origin of LAD or LCX
• Located within an arterial or saphenous vein graft or distal to a diseased (defined as vessel irregularity per angiogram and > 20% stenosed lesion by visual estimation) arterial or saphenous vein graft
• Lesion involving a bifurcation with side branch vessel ≥ 2 mm in diameter, ostial lesion > 40% stenosed by visual estimation or side branch requiring predilation
• Total occlusion (TIMI flow 0), prior to wire passing
• Excessive tortuosity proximal to or within the lesion (extreme angulation (≥ 90°) proximal to or within the lesion)
• Heavy calcification
• Restenotic from previous intervention
• Target vessel is containing thrombus
