Impact of Gestational Age on Surgical Outcomes in Patients With Functionally Single Ventricle

Invited Commentary

“…In this issue of The Annals of Thoracic Surgery, Lee and colleagues 1 from Seoul report that shorter gestation is a risk factor for interstage mortality between initial palliation and the Glenn operation, and the risk continues to decrease with increasing gestation up to 41 weeks. These findings are consistent with data from The Society of Thoracic Surgeons Congenital Heart Surgery Database that showed an odds ratio of 1.34 (95% confidence interval, 1.05-1.71) for in-hospital mortality after cardiac surgery with delivery at 37 to 38 weeks compared with 39.5 weeks' gestation.…”
