Key result
Transcatheter closure of multiple ASDs with multiple ASO devices achieves ~46% immediate complete closure.
Why the study?
Little is known about the use and long-term outcome of multiple Amplatzer Septal Occluder devices to close multiple atrial septal defects.
Does transcatheter closure using multiple ASO devices safely and effectively close multiple atrial septal defects?
Population
33 patients with multiple atrial septal defects, mean age 38.9 years, mean weight 68 kg
Comparison

Does transcatheter closure using multiple ASO devices safely and effectively close multiple atrial septal defects?
Transcatheter closure of multiple ASDs using multiple ASO devices is feasible and effective, though rare but serious complications like device embolization and erosion can occur.
Awad et al. (2007) conducted an observational in Multiple atrial septal defects (ASDs) (n=33). Transcatheter closure using multiple Amplatzer Septal Occluder (ASO) devices was evaluated on Immediate complete closure. Transcatheter closure of multiple atrial septal defects using multiple Amplatzer Septal Occluder devices achieved immediate complete closure in 45.5% of patients and was deemed safe and effective.
