Primary | Target Lesion Failure (TLF) | Defined as the composite of cardiovascular death, target-vessel related myocardial infarction and clinically driven target lesion revascularization. | at 1-year post procedure | |
Secondary | Delivery success | Delivery success is defined as an achievement of successful delivery of study stent to the target lesion, expansion of the study stent and withdrawal of the delivery catheter. | Intraoperative | |
Secondary | Lesion success | Lesion success is defined as the attainment of < 30% residual stenosis by visual estimate and/or < 50% (by QCA) using any percutaneous method (if QCA was not available, the visual estimate of diameter stenosis is used). | Intraoperative | |
Secondary | Device success | Device Success is defined as delivery success with the achievement of a final residual diameter stenosis of the target lesion of < 30% by visual assessment and/or < 50% by QCA, using the assigned device only. | Intraoperative | |
Secondary | Procedure success | Procedure Success is defined as the achievement of < 30% residual stenosis by visual assessment in all target lesions using any percutaneous method without the occurrence of death, Q wave or WHO defined non-Q wave, or repeat revascularization of the target lesion during the hospital stay. | during hospitalization, approximately 3 days | |
Secondary | Target lesion failure (TLF) | The composite of cardiovascular death, MI (not clearly attributable to a nontarget vessel) and clinically driven Target lesion revascularization (TLR). | at index procedure, 30 days, 6 months, 1 year, and 2 years | |
Secondary | Patient oriented composite endpoint (POCE) | Defined as composite of all-cause mortality, any MI and any coronary revascularization. | at index procedure, 30 days, 6 months, 1 year, and 2 years | |
Secondary | Death and subclassifications | Death may be subclassified as: Cardiovascular death, Noncardiovascular death or Undetermined death.
Cardiovascular death may include death caused by acute MI, death caused by sudden cardiac death, including unwitnessed, death resulting from heart failure, death caused by stroke, death caused by cardiovascular procedures, death resulting from cardiovascular hemorrhage, death resulting from other cardiovascular cause. Noncardiovascular death may include death from malignancy, death resulting from pulmonary causes, death caused by infection (including sepsis), death resulting from gastrointestinal causes, death resulting from accident/trauma, death caused by other noncardiovascular organ failure, death resulting from other. Undetermined cause of death is defined as a death not attributable to any other category because of the absence of any relevant source documents. |
at index procedure, 30 days, 6 months, 1 year, and 2 years | |
Secondary | Myocardial infarction and subclassifications | Myocardial infarction - Absolute rise in cardiac troponin (from baseline) =35 times upper reference limit, plus 1 (or more) of the following criteria:
New significant* Q waves or equivalent Flow-limiting angiographic complications New "substantial" loss of myocardium on imaging * Q-wave criteria requires the development of new Q waves =40 ms in duration and =1 mm deep in voltage in =2 contiguous leads. |

Secondary | Revascularization and subclassifications | Successful revascularization of all lesions with angiographically a diameter stenosis = 50% | at index procedure, 30 days, 6 months, 1 year, and 2 years | |
Secondary | Stent thrombosis (ST) and subclassifications | Definite ST

Categorized as: Type 5a Probable bleeding that is clinically suspicious as the cause of death, but bleeding is not directly observed and no autopsy or confirmatory imaging. Type 5b Definite bleeding that is directly observed (clinical specimen or imaging) |
at index procedure, 30 days, 6 months, 1 year, and 2 years | |
Secondary | Balance between bleeding (BARC 3-5) and thrombotic event (myocardial infarction and/or stent thrombosis) | The number of patients with a BARC 3-5 bleeding in comparison to the number of patients with a myocardial infarction and/or a stent thrombosis. | at index procedure, 30 days, 6 months, 1 year, and 2 years | |

Secondary | Quality of Life assessment | Quality of Life assessed as per EuroQl five-dimensional (EQ-5D) questionnaire:
The first part of the questionnaire contain descriptive questions on 5 dimensions: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression, each with 5 levels of responses. The second part of the questionnaire contains a standard vertical 20-cm visual analog scale that is calibrated from 'the worst health you can imagine' (scored 0) at its base to 'the best health you can imagine' (scored 100) at its apex. |
at baseline, 30 days, 6 months, 1 year, and 2 years | |
Secondary | Angina status assessment Seattle Angina Questionnaire (SAQ) | Angina status will be assessed through the Seattle Angina Questionnaire (SAQ).
The SAQ is a validated disease-specific instrument for assessing the health status of patients with coronary artery disease. Scoring: Scores range from 1-100 with higher scores indicating better health |

Secondary | QCA of the index procedure angiogram for a subset of patients with a Complex Bifurcation Lesion (CBL) | Luminal dimensions of bifurcation lesions will be measured by off-line quantitative coronary angiography by a central core laboratory.
The objective of the QCA is to quantitate and express the benefit of the Proximal Optimisation Technique (POT). The POT balloon positioning is of importance in this technique as well as the balloon diameter to obtain optimal stent apposition in the main branch. |
