While percutaneous catheter closure proves an effective treatment for secundum atrial septal defect (ASD2), some child patients require surgical closure. We assessed the risks associated with isolated surgical ASD2 closure by reviewing the outcomes of 120 children operated on between 1999 and 2011 (mean age 4.6 ± 3.9 years, mean weight 17 ± 12 kg). Direct sutures were performed in 4% and patch closures in 96%. The mean cardiopulmonary bypass duration was 38 ± 14 min, aortic cross-clamp time 19 ± 9 min, intensive care unit length of stay 1.6 ± 1.1 days, hospital stay 11.2 ± 5.1 days. There were no complications in 60 patients (50%) and major complications in 8 (6.7%), with 1 patient (0.8%) dying of pneumonia-induced sepsis, 2 (1.7%) requiring revision surgery, 3 (2.5%) requiring invasive treatment (2 pericardial drainage, 1 successful resuscitation), and 2 (1.7%) presenting thromboembolisms (1 cerebral stroke, 1 cardiac thrombus). In hospital minor complications occurred in 22 patients: 17 pericardial effusions (15%), 15 infections requiring treatment (12.5%), 1 sternal instability (0.8%), 4 anemias requiring transfusion (3.3%), 7 pulmonary atelectasis (6%), and 2 post-extubation glottis edema (1.7%). At early outpatient follow-up, complications occurred in 21 patients: 16 (13.3%) pericardial effusions, 4 (3.3%) infections requiring treatment, and 3 (2.5%) keloid scarring. No complications occurred during long-term follow-up. In line with published data, mortality was low (0.8%), yet major complications (6.7%) were more common in these cases than those following percutaneous ASD2 closure. Minor complications were frequent (43%) with no long-term sequelae.
