Abstract
Background
Percutaneous device closure of an ostium secundum atrial septal defect is associated with excellent outcomes and cosmetic results but at the cost of occasional serious and sometimes fatal complications as well as lifelong follow-up. Surgical intervention is required in cases of device-related complications, which carries a slightly higher risk compared to primary closure of an atrial septal defect. We present a surgical perspective of device closure of atrial septal defect.
Methods
Our database was searched over 4 years for complications related to percutaneous device closure of atrial septal defect, which required surgical retrieval of the device and closure of the defect. We identified 14 cases that required surgical intervention.
Results
The median age of the 14 patients was 18 years (range 4–58 years). The size of the defect ranged from 15 to 40 mm (median 30 mm). Device embolization into any part of the cardiovascular system (n = 8) was the most common complication, followed by malalignment of the device (n = 5). One patient had left atrial appendage perforation causing pericardial effusion and cardiac tamponade, and underwent surgical repair. The other 13 patients underwent removal of the device and atrial septal defect closure. One patient developed severe mitral regurgitation requiring mitral valve replacement. There was no mortality.
Conclusion
Although the incidence of device-related complications may be small, they carry a high risk of death or long-term morbidity, even with a small atrial septal defect, unlike primary surgical closure of isolated atrial septal defect.
