Preoperative Venovenous ECMO in an Infant With Late Diagnosis of Hypoplastic Left Heart Syndrome

Late diagnosis and late referral for the Norwood stage 1 procedure in patients with hypoplastic left heart syndromeis rare and associated with a higher mortality. We present a case of a cyanotic almost five-week-old infant with hypoplastic left heart syndrome, highly restrictive foramen ovale, and patent ductus arteriosus, who was bridged with venovenous extracorporeal membrane oxygenationto the Norwood stage 1 procedure.
