Patients
From 1983 to 2014, 870 patients with transposition of the great arteries (TGA) or Taussig-Bing anomaly underwent an ASO for biventricular repair at the Royal Children’s Hospital. Thirty-one patients (3.6%, 31 of 870) weighed less than 2.5 kg at ASO. Mean weight at ASO for the less than 2.5 kg patients was 2.1 kg (median 2.1; range, 1.1 to 2.4). Twenty-nine patients underwent an ASO for TGA, and 2 patients had an ASO for Taussig-Bing anomaly. Mean age at operation was 16 days (median 11; range,

Comment
Despite considerable progress in pediatric cardiac surgery, LBW remains a risk factor for mortality in major pediatric cardiac operations 3, 4, 5. Low body weight infants are often premature and may have complications related to prematurity affecting various systems [6]. Organ immaturity places these infants at a higher risk of infection, renal failure, respiratory disease, cerebral hemorrhage, and necrotizing enterocolitis, to name but a few [1]. Cardiopulmonary bypass is a significant insult
