Background

This is a retrospective and prospective, multi-center, international, post marketing follow-up study to evaluate the safety and efficacy of the Occlutech PDA by using Occlutech Occlusions-Pusher (OOP) in patients with patent ductus arteriosus defects.

Efficacy and safety of implanted device(s) will be evaluated by vital signs, ECGs, and echocardiography data on baseline/implantation visit (include assessments within 36 hrs. post-procedure), Day 30 to Day 90, 6 months to 1 year, 2 years to 3 years after implantation.

Outcome Measures

Primary Outcome Measures  :

  1. Safety primary endpoint [ Time Frame: 1 year ]
    The primary safety endpoint is defined as the incidence of any Serious Adverse Device Effects (SADEs) including procedure-related death, procedure-related stroke, systemic embolism, severe hemolysis, device embolization, cardiac tamponade, infective endocarditis, or vascular complications requiring surgery up to 1-year post-implantation.
  2. Efficacy primary endpoint [ Time Frame: 2 years ]
    The primary efficacy endpoint is defined as successful implantation of the Occlutech® PDA Occluder with a complete closure of the PDA (defined as >90% PDA closure represented by no or small residual flow) as assessed by echocardiography post-implantation) within 2-year post- implantation follow-up.
