Rim Augmentation to Facilitate Gore Distal Disc Cupping for a Large Atrial Septal Defect Closure

Year: 2026

Type: article

Abstract: Transcatheter atrial septal defect (ASD) closure using the GORE® CARDIOFORM ASD Occluder has demonstrated favourable outcomes and no reported cases of erosion, making it an attractive option for closure of large defects with deficient septal rims.(1) During deployment, firm traction of the left atrial disc against the septal tissue (“cupping”) is an essential step that ensures appropriate positioning of the occluder discs across the septum. However, in large defects with minimal rims—particularly the superior rim—adequate cupping may not be feasible, leading to nonseptal device positioning, inadequate rim engagement, and potential need for surgical repair as an alternative closure strategy.
