Abstract
Between January 1985 and November 1998, 270 patients (aged 2 to 220 months) underwent surgical closure of a secundum atrial septal defect. Cardiopulmonary bypass times ranged from 12 to 103 minutes, with aortic crossclamp times of 5 to 49 minutes. Use of blood products decreased from 2.7 units per patient in the first 5 years to 0.2 units in the last 4 years. Median intensive care unit and hospital stays were 2 days and 6 days, respectively. Complications included: bleeding in 6 patients (2%), which required reexploration in 3; air embolism in 1; and arrhythmias in 4. Postpericardiotomy syndrome occurred in 43 patients (16%), requiring drainage in 5. Follow-up (12 to 179 months) was available in 245 patients (91%). There were no early or late deaths. Most patients (94%) were in sinus rhythm, 8 had low atrial rhythm, 3 had first-degree atrioventricular block, and 1 had atrial flutter. Echocardiography in 207 patients (77%) demonstrated a residual shunt in 1 (0.5%), which was hemodynamically insignificant. Late reoperation was required in 4 patients for sternal nonunion. Surgical closure of secundum atrial septal defect remains the gold standard with which transcatheter closure should be compared, particularly with reference to morbidity and residual shunts.
