Should transcatheter closure of atrial septal defects with inferior-posterior deficient rim still be attempted?

摘要

BackgroundTranscatheter closure for atrial septal defect (ASD) with inferior-posterior rim deficiency has been scarcely reported with proper identification of the indications and limits. We aimed to assess the safety and feasibility of transcatheter closure of ASDs with deficient rims, paying particular attention to cases with inferior-posterior rim deficiency.
