Outcome Measures

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Primary Patency at 12 Months [ Time Frame: 12 months ]
    Primary patency is defined as no evidence of restenosis (repeat narrowing) or occlusion (total blockage) within the originally treated lesion based on color-coded duplex sonography (color Doppler ultrasound (CDUS). The Peak Systolic Velocity Ratio must be less than 2.5 (PSVR: the result of taking the highest rate of blood flow within the stented region and dividing it by the highest rate of blood flow just above the stented area).


Secondary Outcome Measures :
  1. Proportion of Subjects Who Experience Major Device-related Adverse Events Within the First 30 Days [ Time Frame: 30 days ]
    If the functioning or characteristics of the device caused or contributed significantly to the adverse event,and if they occurred within 30 days of the procedure, they would be considered major adverse events (MAEs). Major AEs require significant therapy, including an unplanned increase in the level of care, permanent sequelae, hospitalization, or death.

  2. Primary Assisted Patency [ Time Frame: 12 months ]
    Primary assisted patency is defined as patency in the target lesion maintained by repeat intervention (one or more follow-up procedures) in an attempt to salvage the stent prior to complete occlusion (blockage) of the treated arterial segment, and also includes patients with primary patency.

  3. Secondary Patency [ Time Frame: 12 months ]
    Secondary patency is defined as patency in the target lesion maintained by repeat intervention (one more more follow-up procedures) after complete occlusion (blockage) of the treated arterial segment, and also includes patients that have primary and primary assisted patency.

  4. Device-related Major Adverse Events at 12 Months [ Time Frame: 12 months ]
    If the functioning or characteristics of the device caused or contributed significantly to the adverse event (AE), the AE would be related to the device. Major AEs require significant therapy, including an unplanned increase in the level of care, permanent sequelae, hospitalization, or death.
