Design outcomes

Primary

MeasureTime frameDescription
Primary Patency at 12 Months12 monthsPrimary 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

MeasureTime frameDescription
Proportion of Subjects Who Experience Major Device-related Adverse Events Within the First 30 Days30 daysIf 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.
Primary Assisted Patency12 monthsPrimary 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.
Secondary Patency12 monthsSecondary 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.
Device-related Major Adverse Events at 12 Months12 monthsIf 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.

Outcome results

Primary

Primary Patency at 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

Device-related Major Adverse Events at 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.

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.
