Large secundum atrial septal defects (ASDs) may lead to congestive heart failure, frequent respiratory infections, and growth retardation in infants, while they may cause the symptoms of fatigue and dyspnea in children. The procedure of transcatheter closure of secundum ASD has been used as a safe, alternative method to surgery over the last two decades. However, transcatheter closure of large ASDs is difficult and usually requires multiple attempts before the device is satisfactorily deployed. Inappropriate deployment of the device results in failure of the procedure, particularly in cases of large ASDs with deficient rim and the fluoroscopy time lengthens as a result of repetitive attempts. Occasionally, embolization of the device occurs as a complication of the procedure. Several methods have been defined for safer and successful transcatheter closure of large secundum ASDs in the literature.
In this month’s Journal of Invasive Cardiology, we describe a “new modified balloon-assisted technique’’ in order to prevent prolapse of the device to the right atrium in such cases. In addition to this, we also compared the results of this technique with the conventional method. These were all written in light of the previously published literature, which is summarized therein.
