Outcome results

Primary

The Primary Effectiveness Endpoint is the Rate of Complete Closure of the Ductus Arteriosus at the Six-month Follow-up.

The primary efficacy endpoint is the rate of complete closure of the ductus arteriosus as assessed by the absence of residual flow and continuous murmur at the six-month follow-up by transthoracic echocardiography and physical exam respectively.

Time frame: 180 days

Population: Of the 192 enrolled, 178 subjects experienced successful device placement.Of the 178 subjects with the device implanted,166 had a 6-month TTE and physical examination before 200 days post procedure or had an explant before the 6-month follow-up interval ended.

The Primary Safety Endpoint is the Rate of Device and Procedure Related Serious Adverse Events (SAE) 180 Days Post Procedure.

The primary safety endpoint is the rate of device and/or procedure related SAEs reported in subjects whom device placement is attempted from the procedure through 180 days post procedure SAEs are defined as: Adverse events resulting in the following; death, life-threatening adverse event, inpatient hospitalization or prolongation of existing hospital stay, persistent or significant disability/incapacity or medically significant event.

Time frame: 180 days

Population: Of the 192 enrolled subjects, 188 completed follow-up through 180 days post procedure;3 subjects were lost to follow-up (LTFU) before the 180-day interval and 1 subject was discontinued at the end of the 6-month visit without follow-up.
