title: Outcome following repair of sinus venosus atrial septal defects in children.
abstract: The outcome of surgical repair of sinus venosus atrial septal defect was reviewed retrospectively. The operation was performed on 44 children aged 8 to 163 months, between April 1985 and November 1998. Median cardiopulmonary bypass and aortic crossclamp times were 58 minutes (range, 29 to 141 minutes) and 29 minutes (range, 4 to 67 minutes), respectively. Use of blood products decreased from 4.5 units per patient in the first period (1985 to 1989) to 0.6 units in the last period (1995 to 1998). Median intensive care and hospital stays were 2 days (range, 1 to 12 days) and 6 days (range, 4 to 16 days), respectively. There was 1 early death (2.3%). Complications included reexploration for bleeding in 2 patients (4.5%) and for superior vena cava obstruction in 1 (2.3%), and arrhythmias in 3 (6.8%), which required a pacemaker in one. During follow-up of 15 to 176 months, 83.8% of patients were in sinus rhythm. One required angioplasty for superior vena cava stenosis, hemodynamically insignificant residual shunt was found in 3, and mild superior vena cava stenosis in 3. Repair of sinus venosus atrial septal defect carries a low mortality and morbidity, but long-term follow-up is needed to monitor potential sinus node dysfunction and superior vena cava stenosis.
