Key result
Among 1,921 adults undergoing transcatheter atrial septal defect closure, acute complications were rare, with device migration occurring in 0.4% of patients and no instances of cardiac erosion.
Why the study?
This study investigated current trends in transcatheter ASD closure among adult patients, focusing on device and size selection as well as acute complications.
Observational (n=1,921)
Yes
Transcatheter ASD closure in adults using contemporary devices demonstrates a very low rate of acute complications, with device migration occurring in 0.4% of cases.

Device migration occurs regardless of oversizing in transcatheter ASD closure; leaves open optimal device selection strategies.
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: 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.

Tanaka et al. (2025) conducted an observational in Atrial septal defect (n=1,921). Transcatheter atrial septal defect closure was evaluated on Acute complications (device migration, erosion, atrioventricular block, death). Among 1,921 adults undergoing transcatheter atrial septal defect closure, acute complications were rare, with device migration occurring in 0.4% of patients and no instances of cardiac erosion.
