Clinical Device Success (Per Lesion)On day 0 (the day of procedure)

Successful delivery and deployment of the Clinical Investigation scaffold at the intended target lesion and successful withdrawal of the scaffold delivery system with attainment of final residual stenosis of less than 50% of the target lesion by QCA (by visual estimation if QCA unavailable). Standard pre-dilation catheters and post-dilatation catheters (if applicable) may be used. Bailout patients will be included as device success only if the above criteria for clinical device are met.

Successful delivery and deployment of the Clinical Investigation scaffold at the intended target lesion and successful withdrawal of the scaffold delivery system with attainment of final residual stenosis of less than 50% of the target lesion by QCA (by visual estimation if QCA unavailable) and/or using any adjunctive device without the occurrence of ischemia-driven major adverse cardiac event (MACE) during the hospital stay with a maximum of first seven days post index procedure.

Hierarchical Target Vessel Failure (TVF)5 years

Target Vessel Failure (TVF) is the composite of Cardiac Death, Myocardial infarction (MI) or Ischemic-Driven Target Vessel Revascularization (ID-TVR).

Major adverse cardiac events (MACE) is defined as the composite of cardiac death, all myocardial infarction,and clinically indicated target lesion revascularization (CI-TLR).

Cardiac death is defined as any death in which a cardiac cause cannot be excluded.

(This includes but is not limited to acute myocardial infarction, cardiac perforation/pericardial tamponade, arrhythmia or conduction abnormality, cerebrovascular accident within 30 days of the procedure or cerebrovascular accident suspected of being related to the procedure, death due to complication of the procedure, including bleeding, vascular repair, transfusion reaction, or bypass surgery.)

Myocardial Infarction5 years

Myocardial Infarction (MI):

* Q wave MI: Development of new, pathological Q wave on the ECG.

* Non-Q wave MI: Elevation of CK levels to ≥ two times the upper limit of normal (ULN) with elevated CK-MB in the absence of new pathological Q waves.

Late Incomplete Apposition3 year

Late-Acquired Incomplete Apposition is defined as incomplete apposition of the scaffold at follow-up, which was not present post-procedure.

Incomplete Apposition: Failure of the scaffold to completely appose to the vessel wall after placement is defined as one or more scaffold strut separated from the vessel wall with evidence of blood speckles behind the strut in the ultrasound image.

Scaffold Thrombosis5 years

Scaffold thrombosis will be categorized as acute (≤ 1day), subacute (\>1day ≤ 30 days) and late (\>30 days) and will be defined as any of the following:

* Clinical presentation of acute coronary syndrome with angiographic evidence of scaffold thrombosis (angiographic appearance of thrombus within or adjacent to a previously treated target lesion)

* In the absence of angiography, any unexplained death, or acute MI (ST segment elevation or new Q-wave)\* in the distribution of the target lesion within 30 days \*(Non-specific ST /T changes and cardiac enzyme elevations do not suffice)

Any thromboses that occur less than 30 days after the index procedure will not be counted as restenosis.
