Current Primary Outcome Measures
 (submitted: December 17, 2019)
  • Vascular Access Complications (Safety) [ Time Frame: 6 months ]
    Access vessel complications include femoral arterial or femoral/jugular venous complications noted during the procedure, immediately after the procedure or delayed (>24 hours). They range from bleeding from access sites, arterial or venous thrombosis with or without the need for treatment to loss of limb secondary to arterial occlusion.
  • Valvular Injury (Safety) [ Time Frame: 6 months ]
    Valvular injury includes damage to the tricuspid valve or other cardiac valve resulting in immediate post-procedural valvular dysfunction.
  • Device Embolization (Safety) [ Time Frame: 6 months ]
    Device embolization includes malposition of the device either during or after the procedure or delayed (>24 hours). The outcome of device embolization ranges from observation, transcatheter retrieval at time of procedure or at a separate time, surgical retrieval, other end organ damage, to mortality.
  • Pulmonary or Aortic Vessel Stenosis (Safety) [ Time Frame: 6 months ]
    Adjacent vessel stenosis includes a narrowing of the aorta or the left pulmonary artery directly as a consequence of device implantation for PDA closure. Vessel stenosis could happen either during or after the procedure or delayed (>24 hours). The outcome of vessel stenosis ranges from no intervention needed to repeated transcatheter and surgical therapies.
  • Rate of Effective PDA Closure (Effectiveness) [ Time Frame: 6 months ]
    The effectiveness endpoint is the rate of effective closure of the PDA using a transcatheter device within six months post procedure. If more than one attempt is required, or multiple devices are required during the same procedure, it is still considered effective if there is Grade 0 or Grade 1 shunt, as defined below, at follow-up by transthoracic echocardiography or if a second procedure is not required following the initial attempt. If there is device embolization, adjacent vessel stenosis that required retrieval of the device and replacement during the same procedure with less than Grade 1 shunt during follow-up, it is still considered effective. Conversely, if an AE is noted after the procedure that requires a second procedure for treatment that results in greater than Grade 1 shunt, then the procedure is considered not effective, even if the initial attempt was effective. See protocol for PDA shunt definitions.

Current Secondary Outcome Measures
 (submitted: December 17, 2019)
  • Significant obstruction of the left pulmonary artery [ Time Frame: 6 months ]
    Significant obstruction of the left pulmonary artery is defined as less than 30% flow to the left lung by lung perfusion scan or a peak instantaneous gradient in left pulmonary artery ≥35 mmHg by echocardiogram if lung perfusion scan is not available or as determined by the interventional cardiologist based on angiographic appearance.
  • Significant obstruction of the aorta [ Time Frame: 6 months ]
    Significant obstruction of the aorta is defined as a gradient of ≥20 mmHg in the aortic isthmus by invasive aortic catheterization or a mean gradient ≥20 mmHg in the aortic isthmus by echocardiogram if invasive aortic catheterization is not available.

Descriptive Information
Brief Title The U.S. PDA Registry
Official Title The United States Patent Ductus Arteriosus Registry
Brief Summary The objective of this study is to demonstrate the continued safety and efficacy in a real-world setting of transcatheter device closure of the PDA in premature infants less than 2kg in weight at the time of device implant using the Amplatzer Piccolo Occluder device and other devices performed in the USA.
Detailed Description Based on the IMPACT registry, there are over 6000 transcatheter device closures of PDA that occurs in the United States annually. However, there are no comprehensive data collection tools for this procedure. The current databases do not include multiple data points, or follow-up data, or a section for specific adverse events to be documented. Moreover, until now, there has been no approved devices for PDA closure in children < 2kg. This clinical study is the first of its kind to collect data from all transcatheter device closure of PDA in children < 2kg performed in the USA.This study will be limited to children between 700 to 2000 grams who are the most vulnerable population undergoing this procedure. This will allow us to understand the real world experience (efficacy and safety) of using the Amplatzer Piccolo Occluder and other devices in an extremely vulnerable, yet highly underserved population. The study will allow for standardization of this procedure throughout the country for the small children (<2 kg) with a PDA. This is a multi-center, single arm, observational data collection study. This will be a large population study to help analyze outcomes in subjects <2 kg. The trial has two primary endpoints for safety and effectiveness without formal hypothesis. The safety and effectiveness results will be compared with data reported in the ADO II AS IDE and Continued Access Protocol studies.

Plan Description: A Data Management Plan (DMP) will describe procedures used for data review, database cleaning, and issuing and resolving data queries. If appropriate, the DMP may be updated throughout the clinical investigation duration. All revisions will be tracked and document controlled. Subject data will be captured in a validated electronic data capture (EDC) system. Only authorized site personnel will be permitted to enter the CRF data through the EDC system.
