Procedural Characteristics and Outcomes of Transcatheter Interventions for Aortic Coarctation: A Report From the IMPACT Registry

BackgroundAlthough surgical repair was the traditional first-line treatment for native coarctation of aorta (CoA), balloon angioplasty (BA) and stenting are now increasingly being performed. We aimed to determine practice patterns acute outcomes transcatheter interventions in largest multicenter registry congenital catheterization.MethodsCoA from IMPACT (IMproving Pediatric Adult Congenital Treatment) National Cardiovascular Data Registry were analyzed. The procedure choice compared among patients with no prior on aortic isthmus (native CoA). Procedural success defined as major adverse events (MAEs) a final peak gradient <20 mm Hg optimal outcome MAEs <10 Hg.ResultsOver 8-year study period, 5928 CoA procedures performed, which 1187 performed CoA. In this group, more then half children aged >1 year >90% those >8 years. achieved but only 69% BAs. Stent implantation associated higher likelihood (<10 Hg) after adjustment age baseline characteristics. most common <1 (14%), occurred 2% 2.5% 1 18 years 6.6% adults (P < .001), likely BA than (odds ratio, 0.5; 95% CI, 0.28-0.9; unadjusted P = .02).ConclusionsCatheter safely older adults, high degree immediate procedural success, particularly stenting.
