Foranstaltningsbeskrivelse
Tidsramme
Target Vessel Revascularization at 9 Months
Tidsramme: 9 months
Target vessel revascularization (TVR) was defined as percutaneous revascularization or bypass of the target lesion or any segment of the artery containing the target lesion. The percentage of participants requiring revascularization of the target vessel was determined by stenosis of > 50% confirmed by angiography.

Tidsramme
Systolic Velocity Ratio (SVR) > 2.0
Tidsramme: 9 months
The percentage of participants with a systolic velocity ratio > 2.0 assessed using lower extremity arterial duplex ultrasound.
9 months
Change From Baseline in Walking Impairment Questionnaire (WIQ) Score
Tidsramme: Baseline and Month 9
The Walking Impairment Questionnaire (WIQ) is utilized to characterize a patient's walking ability. Scores range from 0 (no difficulty) to 100 (much difficulty).
Baseline and Month 9
Decrease in Ankle Brachial Index (ABI) > 0.15
Tidsramme: Baseline and Month 9

The percentage of participants with a decrease in the Ankle Brachial Index (ABI) > 0.15.

Ankle Brachial Index = Systolic Ankle Pressure / Systolic Brachial Pressure.

Baseline and Month 9
Target Lesion Revascularization (TLR) at 9 Months
Tidsramme: 9 months
Target lesion revascularization (TLR) was defined as repeat percutaneous intervention or bypass surgery of the previously treated target lesion (or blockage). The percentage of participants requiring revascularization of the target lesion was determined by stenosis of > 50% confirmed by angiography.

Number of Deaths
Tidsramme: Up to 11 months
Number of patients who died due to any cause.
Up to 11 months
Number of Participants With Myocardial Infarction (MI)
Tidsramme: Up to 11 months
The number of patients experiencing Myocardial Infarction (MI) during the study. Myocardial Infarction was defined as new pathologic Q waves of at least 0.04 seconds, or an increase in serum creatine kinase to more than twice the normal code together with a pathologic increase in myocardial isoenzymes.
Up to 11 months
Number of Participants With a Stroke
Tidsramme: Up to 11 months
The number of patients experiencing a stroke during the study. Stroke was defined as any sudden development of neurological deficits lasting more than 24 hours, and if a brain imaging study is performed it shows an infarction or hemorrhage. A transient ischemic attack is a neurological deficit lasting less than 24 hours and, if an imaging study is performed, shows no evidence of infarction or hemorrhage.
Up to 11 months
Minimum Lumen Diameter
Tidsramme: 9 months
Minimum lumen diameter (MLD) is defined as the smallest diameter in millimeters (mm) in the arterial segment of interest measured angiographically.
9 months
Late Loss
Tidsramme: Day 1 (following revascularization) and 9 months
Late loss is defined as minimum lumen diameter (MLD) immediately post-procedure minus MLD at the time of follow-up, in mm.
Day 1 (following revascularization) and 9 months
Percentage of Participants With Binary Restenosis
Tidsramme: 9 months
Binary restenosis was defined by a >50% diameter stenosis at follow-up study, assessed by angiography.
9 months
Diameter Stenosis
Tidsramme: 9 months
Diameter stenosis is calculated as [1 - (minimum lumen diameter (MLD) / reference vessel diameter)] * 100, where the reference vessel diameter is the vessel diameter measured in a healthy segment of the target vessel proximal as close as possible to the lesion.
