Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 12-month duplex-ultrasound defined target lesion patency will be assessed in the enrollment arm. Patency is defined as a ratio of less than 2.0, measured as the upstream peak systolic velocity compared with PSV in the area of greatest stenosis. | 12 months |
Secondary
| Measure | Time frame |
|---|---|
| Target lesion revascularization will be evaluated at 12 mos. and defined as any pecutaneous or surgical intervention to treat a stenosis or cocclusion of the arget lesion treated at the index procedure. | 12 month follow up |
