Background: Transcatheter atrial septal defect (ASD) closure is the first treatment option for secundum ASD, but parameters for optimal device selection have not been established. We compared outcomes between occluders with a wire frame and metal mesh devices.Methods and Results: This study included secundum ASD patients implanted with a wire frame occluder (GORE®CARDIOFORM ASD occluder [GCA]; W.L. Gore & Associates) or metal mesh devices (Amplatzer septal occluder device [Abbott] and Occlutech Figulla Flex II device [Occlutech]). The presence of residual shunt and B-type natriuretic peptide (BNP) levels after implantation were compared. Of the 970 patients with either GCA (n=48) or a metal mesh device (n=922; control), 42 patients from each group were analyzed after propensity score matching. The prevalence of residual shunt was significantly lower in the GCA group 1 day and 1 month after implantation (P<0.001 and P=0.017, respectively), whereas there was no significant difference between the 2 groups 6 months later (P=0.088). BNP levels at 1 month were significantly higher in the GCA group (ratio of change 1.36; 95% confidence interval [CI] 1.01–1.83), but did not differ significantly between the 2 groups at 6 months (ratio of change 1.04; 95% CI 0.65–1.65).Conclusions: Patients implanted with a wire frame occluder had a lower prevalence of residual shunt and a greater increase in BNP levels in the early period after implantation.
