Background: This study investigated current trends in transcatheter atrial septal defect (ASD) closure among adult patients, with an emphasis on device and size selection, as well as acute complications.
Methods and Results: This study used the Japanese Structural Heart Disease (J-SHD) registry database, which is a prospective nationwide multicenter registry. In all, 1,921 patients who underwent transcatheter ASD closure between 2019 and 2022 were analyzed in this study. The specifics of the procedures, including device type, size selection, and acute complications, were assessed. The mean (±SD) age of participants was 57±18 years, with 37.6% being male. Aortic rim deficiency was observed in most patients (50.3%). The prevalence of aortic rim deficiency was 32.5% for the Amplatzer®Septal Occluder (ASO), 65.6% for the Occlutech®Figulla Flex II Septal Occluder (FSO), and 57.8% for the GORE®CARDIOFORM ASD Occluder. In patients in whom the ASO or FSO was used, device size was 2–3 and 5–6 mm larger than defect size, respectively. Device migration was observed in 8 (0.4%) patients, and occurred regardless of device oversizing or undersizing relative to defect size.
Conclusions: This study reports the trends in clinical features, device and size selection, and acute complications in adult patients who underwent transcatheter ASD closure.
