Design outcomes

Primary

MeasureTime frameDescription
Peripheral Arterial Cohort30 daysFreedom from major (above-ankle) unanticipated amputation of the index limb
Peripheral Venous Cohort30 daysTreated limb improvement at 30 days, defined as no unplanned intervention for breakthrough re-thrombosis and improvement in Villalta score relative to baseline.
Pulmonary Embolism (PE) Cohort30 DaysNormal right ventricular function at 30 days follow-up, defined as tricuspid annular plane systolic excursion (TAPSE) \>1.7cm , measured on transthoracic echocardiography (TTE) and independently adjudicated.

Secondary

MeasureTime frameDescription
Peripheral Arterial Cohort90 DaysFreedom from major (above-ankle) amputation of the index limb
Peripheral Venous CohortIntraproceduralTechnical success defined as complete or near complete (\>75%) reduction in Marder score from baseline to immediately after the use of the device and prior to any use of adjunctive device, as independently adjudicated
Pulmonary Embolism CohortIntraproceduralChange in pulmonary artery pressure
