Yang S, et al. - In infants less than 365 days of age, researchers ascertained if age at complete repair of tetralogy of Fallot (TOF) impacts postoperative morbidity and length of hospital stay. The United States Nationwide Inpatient Sample was searched for infants 0–365 days of age who had complete repair of TOF between 2005 and 2011. Based on age at the time of repair, patients were categorized as 0–30 days, 31–90 days, 91–180 day, and > 180 days. The study included a total of 1,112 infants. Investigators found that postoperative complications and length of hospital stay were affected by the timing of complete repair of TOF in children < 1 year old. In infants ≥91 days old at time of repair vs those ≤30 days old, the risk of postoperative complications was 40% lower, as seen in multivariate analysis. A significantly shorter length of hospital stay was seen in children > 30 days old at the time of repair vs those aged ≤30 days.
