Ductus Arteriosus, Patent

Patent Ductus Arteriosus is a developmental condition commonly observed among preterm infants. It is a condition where the opening between the two major blood vessels leading from the heart fail to close after birth. In the womb, the opening (ductus arteriosus) is the normal part of the circulatory system of the baby, but is expected to close at full term birth. If the opening is tiny, the condition can be self-limiting. If not, medications/surgery are options for treatment. There are two ways to treat patent ductus arteriosus - one is through closure of the opening with an FDA approved device called PICCOLO, the other is through supportive management (medications). No randomized controlled trials have been done previously to see if one of better than the other. Through our PIVOTAL study, the investigators aim to determine is one is indeed better than the other - if it is found that the percutaneous closure with PICCOLO is better, then it would immediately lead to a new standard of care. If not, then the investigators avoid an invasive costly procedure going forward.

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.
