Measure
Catheter-closure of PDA
Infants randomized to this group will undergo a catheter procedure to close hemodynamically-significant patent ductus arteriosus (HSPDA). Cather closure of patent ductus arteriosus (PDA): Infants assigned to this group will have a catheter run from a blood vessel in the upper leg / groin area to the heart, where an FDA-approved device will be placed within the patent ductus arteriosus to occlude or plug it, thereby closing the ductus.
Conservative Management of PDA
Infants randomized to this group will be treated to reduce the symptoms of a hemodynamically-significant patent ductus arteriosus (HSPDA), in the hopes that over time the HSPDA will become reduced in size (to the point of no longer meeting criteria for being "hemodynamically significant") or close naturally. Infants in this group with declining health status attributable to a PDA which meet qualifying criteria may receive catheter closure (intervention) if deemed medically necessary. Cather closure of patent ductus arteriosus (PDA): Infants assigned to this group will have a catheter run from a blood vessel in the upper leg / groin area to the heart, where an FDA-approved device will be placed within the patent ductus arteriosus to occlude or plug it, thereby closing the ductus. Conservative management of patent ductus arteriosus (PDA): Infants with a hemodynamically-significant patent ductus arteriosus randomized to this group will be treated by fluid restriction and possible diuretic use to reduce PDA symptoms, and allow time to permit the PDA to close or become reduced in size to the point where it is no longer considered "hemodynamically-significant".

PRIMARY outcome

Timeframe: Weekly for 1 month pre-closure (intervention group) or corresponding time point (non-intervention group); Weekly for 1 month post-closure (intervention group) or corresponding time point (non-intervention group); 36 weeks corrected gestational age

Population: Single participant enrolled in preliminary trial, randomized to conservative management group. Period specified as outcome is the time (in weeks) post-randomization / group assignment that the subject continued to require ventilatory (SIMV) support.

Period the participant is in need of ventilator support \[Synchronized Intermittent Mandatory Ventilation (SIMV), High Frequency Oscillatory Ventilation (HFOV), or similar\]

Time on Ventilatory Support Required
4 weeks

PRIMARY outcome

Timeframe: Post-randomization (up to 6 weeks) for participants in both groups.

Population: Supplemental oxygen required while undergoing assigned treatment. If assignment was to the Conservative management group and rescue intervention was needed, this applies to the period prior to intervention. The calculation begins using the percentage oxygen on timepoint 0 (day 1, enrollment and randomization) using the weekly supplementary oxygen percentages (on day 7, day 14, day 21, etc up to day 56 post-randomization).

Weekly supplemental oxygen support required (in % fraction of inspired oxygen, FiO2)
