Key result
Transcatheter placement of a PDA occluder was less effective for initial closure (77.3% vs 99.8%) and more costly ($11,466 vs $8,838) than conventional surgical closure.
Why the study?
Does transcatheter implantation of the Rashkind PDA occluder improve closure rates and reduce costs compared to conventional surgical closure in patients with isolated patent ductus arteriosus?
Cohort (n=631)
Yes
Does transcatheter implantation of the Rashkind PDA occluder improve closure rates and reduce costs compared to conventional surgical closure in patients with isolated patent ductus arteriosus?
Absolute Event Rate: 77.3% vs 99.8%
Surgical closure of isolated patent ductus arteriosus was found to be more effective and less costly than transcatheter placement of the Rashkind PDA occluder.

Favors surgical PDA closure in this cohort; leaves open randomized trials of modern devices.
Gray et al. (1993) conducted a cohort in Patent ductus arteriosus (n=631). Transcatheter implantation of the Rashkind PDA occluder vs. Conventional surgical closure was evaluated on Closure of the ductus arteriosus after the initial procedure. Transcatheter placement of a PDA occluder was less effective for initial closure (77.3% vs 99.8%) and more costly ($11,466 vs $8,838) than conventional surgical closure.
