Background: The purpose of this study was to compare the outcomes of surgical closure and catheter closure of atrial septal defects (ASDs) using an Amplatzer Septal Occluder in patients 40 years of age or older.
Methods: Seventy-three patients underwent catheter closure (group D), and 27 patients underwent surgical closure of ASDs (group S). The echocardiogram, catheter, and electrocardiogram data were compared.
Results: The patients in group D were older at the time of closure (P=0.004) and had smaller ASD diameters (P<0.001) than the patients in group S. There was no mortality due to cardiac events in either group. The group D patients had significantly shorter hospital stays (P<0.001). The incidence of postoperative atrial arrhythmias was significantly lower in group D (P=0.015). Conclusions: Despite the implantation of a foreign body inside the heart, catheter closure contributed to a lower incidence of postoperative atrial arrhythmias. These findings may influence the long-term clinical outcomes of adult patients with ASDs.
