Abstract

Abstract : Objectives: To assess the safety and efficacy of the Gore Septal Occluder (GSO) used for device‐closure of significant secundum‐type atrial septal defects (ASD II) focusing on pediatric patients. Background: The GSO is a patch‐like double disc device. Due to its design, it is assumed to be safe, even when implanted in ASDs with deficient retro‐aortic rims. Methods: Multicenter retrospective analysis of consecutive children and adolescents with a GSO in situ for at least 12 months according to a 1‐ to 4‐year midterm follow‐up. Results: Hundred and seventy three pediatric patients were enrolled. At implantation, median age was 6 years (range 0.7–17.9), median body weight and length were 21 kg (6.4–95) and 119 cm (65–193). Median follow‐up period was 20 months (range 12–51). ASD anatomy was comprised of single defects in 131 patients (76%), multi‐fenestrated defects in 42 (24%), and deficient retro‐aortic rims in 33 (19%). Follow‐up confirmed an overall closure‐rate of 95.4%. Small residual shunts were reported in eight patients (4.6%) without need for any re‐intervention. Complications were classified as minor events both during the initial procedure (9 patients, 5.2%) and on follow‐up (another 9 patients), including transient AV block II in three patients (1.8%) and four snare‐retrievals (2.4%) during the initial procedure. Conclusions: Periprocedural and midterm follow‐up data have shown the GSO to be effective and safe for ASD device closure in children and adolescents. GSO may be considered the first‐choice device in deficient retro‐aortic rims and multi‐fenestrated defects, when covering most of the atrial septum is necessary. © 2016 Wiley Periodicals, Inc.
