Comparison of the Angiographic Result of the Orsiro Hybrid Stent With Resolute Integrity Stent

All-cause mortality at 12 months follow-up

Cardiac death at 12 months follow-up. Any death due to proximate cardiac cause (eg, MI, low-output failure, fatal arrhythmia), unwitnessed death and death of unknown cause, and all procedure-related deaths, including those related to concomitant treatment, will be classified as cardiac death.

Any target lesion revascularization (TLR), defined as repeat revascularization within the stented segment including 5 mm proximal and distal border zones.

TLR is defined as any repeat percutaneous intervention of the target lesion or bypass surgery of the target vessel performed for restenosis or other complication of the target lesion. All TLRs should be classified prospectively as clinically indicated* or not clinically indicated by the investigator prior to repeat angiography. An independent angiographic core laboratory should verify that the severity of percent diameter stenosis meets requirements for clinical indication and will overrule in cases where investigator reports are not in agreement. The target lesion is defined as the treated segment from 5 mm proximal to the stent and to 5 mm distal to the stent.

Target vessel revascularization, defined as any revascularization of treated vessel.

TVR is defined as any repeat percutaneous intervention or surgical bypass of any segment of the target vessel. The target vessel is defined as the entire major coronary vessel proximal and distal to the target lesion, which includes upstream and downstream branches and the target lesion itself.

Myocardial infarction (MI) was defined according to the ARC definitions and an extended historical protocol definition.

Target vessel related MI is defined as MI, which developed in previously treated vessel.

Myocardial infarction (MI) was defined according to the ARC definitions and an extended historical protocol definition.

Non-target vessel related myocardial infarction is defined as MI, which developed in non-target vessel.

Clinical Device Success is defined as an achievement of a final residual diameter stenosis of < 30% at the in-stent segment by online quantitative angiography or visual estimation, without device failure or malfunction. A device is considered to have failed if it did not meet the requirements of the definition for clinical device success.

Clinical Lesion Success is defined as an achievement of a final in-stent segment diameter stenosis < 30% by online QCA or visual assessment over the entire stent length, with TIMI-3 flow and no more than an NHLBI type C dissection in the analysis segment

Clinical Procedure Success is defined as an achievement of a final in-stent segment diameter stenosis < 30% by online QCA or visual assessment over the entire intervened vessel segment, with TIMI-3 flow and no more than an NHLBI type C dissection with or without any adjunctive devices, and without the occurrence of cardiac death, target vessel MI (Q-wave and non Q-wave MI), or repeat revascularization of the target lesion during the health care facility stay.

ARC definition of stent thrombosis is classified and defined as follows. Definite/Confirmed stent thrombosis refers angiographic or pathologic confirmation of partial or total thrombotic occlusion within the per-stent region with either i) acute ischemic symptoms, ii) ischemic EKG changes, iii) elevated cardiac biomarkers. Probable stent thrombosis is defined as any unexplained death within 30 days of stent implantation or any myocardial infarction, which is related to documented acute ischemia in the territory of the implanted stent without angiographic confirmation of stent thrombosis and in the absence of any other obvious cause. Possible stent thrombosis is defined as any unexplained death beyond 30 days of stent implantation.

Target lesion failure defined as a composite of cardiac death, myocardial infarction (not clearly attributed to a nontarget vessel), or clinically indicated target lesion revascularization by percutaneous or surgical methods at 1 years.

Patient-oriented composite outcome included all-cause mortality, any MI (including nontarget vessel territory), and any revascularization (including all target and nontarget vessels, regardless of percutaneous or surgical methods).

Percent diameter stenosis in the in-stent and in-segment zone.

All QCA measurements of the target lesion will be obtained in the in-stent zone, and over entire segment including the stent and its 5 mm proximal and distal margins (in-segment zone).

Binary restenosis is defined as stenosis of 50% or more at follow-up angiography). All QCA measurements of the target lesion will be obtained in the in-stent zone, and over entire segment including the stent and its 5 mm proximal and distal margins (in-segment zone).

Clinically driven revascularization is considered clinically indicated if angiography at follow-up shows a percent diameter stenosis ≥ 50% (core laboratory quantitative coronary angiography assessment) and if one of the following occurs: (1) A positive history of recurrent angina pectoris, presumably related to the target vessel; (2) Objective signs of ischemia at rest (ECG changes) or during exercise test (or equivalent), presumably related to the target vessel; (3) Abnormal results of any invasive functional diagnostic test (eg, Doppler flow velocity reserve, fractional flow reserve); (4) A TLR or TVR with a diameter stenosis ≥ 70% even in the absence of the above-mentioned ischemic signs or symptoms.
