N2 - Background: Concern regarding aortic erosion has focused attention on the retro-aortic rim in patients undergoing device closure of atrial septal defects (ASD), but its effect on early outcomes is not well studied. Methods: A multicenter retrospective cohort study of patients undergoing device occlusion of ASD between 1/2011-10/2014 was performed, using data from the IMproving Pediatric and Adult Congenital Treatment Registry. Subjects were divided between those with retro-aortic rim <5 and ≥5 mm. Primary outcomes were technical failure and major early adverse events. Case times were measured as surrogates of technical complexity. The effect of deficient retro-aortic rim on primary outcomes was assessed using hierarchical logistic regression, adjusting for other suspected covariates and assessing whether they represent independent risk factors. Results: 1,564 subjects (from 77 centers) were included, with deficient retro-aortic rim present in 40%. Technical failure occurred in 91 subjects (5.8%) and a major early adverse event in 64 subjects (4.1%). Adjusting for known covariates, the presence of a deficient retro-aortic rim was not significantly associated with technical failure (OR: 1.3, 95% CI: 0.9–2.1) or major early adverse event (OR: 0.7, 95% CI: 0.4–1. 2). Total case (P = 0.01) and fluoroscopy time (P = 0.02) were greater in subjects with deficient rim, but sheath time was not significantly different (P = 0.07). Additional covariates independently associated with these outcomes were identified. Conclusion: Deficient retro-aortic rim was highly prevalent but not associated with increased risk of technical failure or early adverse events. Studies with longer follow-up are necessary to assess other outcomes, including device erosion.
