ABSTRACT
OBJECTIVES:
To assess the structural integrity of the patch-like Gore Septal Occluder (GSO) used for device closure of secundum-type atrial septal defects (ASD II) in pediatric patients.BACKGROUND:
GSO has shown to be effective and safe for ASD device closure in children and adolescents.METHODS:
Single-center, retrospective mid- to long-term follow-up of all children and adolescents with a GSO in situ (≥12 months). Periprocedural data and follow-up data were evaluated, including chest X-rays to assess the GSO's wire-frame morphology.RESULTS:
Ninety-one consecutive patients were enrolled with a median age and weight of 5 years (range 2-18) and 20 kg (range 11-95) at implantation. ASD anatomy included 64 single and 27 multi-fenestrated defects, with 39 patients having small retro-aortic rims (≤4 mm). Median follow-up period was 42.5 months (range 12-74). Chest X-rays were available in 80 children in 74 of them, the GSO's visualization on X-ray enabled us to reliably assess the wire-frame structure. Wire-frame fracture (WFF) was ultimately detected in five of the 74 patients (6.8%); however, those occluders appeared stably anchored and well aligned to both sides of the septum, and no free wire fragments had escaped the GSO matrix. Thus, no further treatment was required.CONCLUSIONS:
Our data confirm that the GSO is safe and effective for ASD closure. Despite its lightweight construction, the GSO seems to offer reliable mechanical durability. Wire-frame fractures occur, but the free wire-ends appear to have remained stable within the GSO matrix without any clinical sequelae so far.Palabras clave
