ABSTRACT
Secundum atrial septal defects (ASDs) are a common congenital abnormality and are amongst the most common congenital heart defects to present in adulthood. The development of transcatheter strategies for treatment of interatrial defects has allowed for effective closure of ASDs; these therapies offer advantages in terms of morbidity, hospital length of stay, and anesthesia duration compared to surgical closure,1-7 with earlier hemodynamic improvement compared to surgical intervention.8 The effectiveness of these devices has been demonstrated in both adult patients,9 including those greater than 40 years of age,10 as well as pediatric populations.11 As such, percutaneous ASD closure has become the preferred treatment option in cases where it is feasible.
