Surgical Management and Outcomes of Ebstein Anomaly in Neonates and Infants: A Society of Thoracic Surgeons Congenital Heart Surgery Database Analysis.
BACKGROUND: Ebstein anomaly (EA) encompasses a broad spectrum of morphology and clinical presentation. Those who are symptomatic early in infancy are generally at highest risk, but there are limited data regarding multicentric practice patterns and outcomes. We analyzed multiinstitutional data concerning operations and outcomes in neonates and infants with EA. METHODS: Index operations reported in The Society of Thoracic Surgeons Congenital Heart Surgery Database (2010 to 2016) were potentially eligible for inclusion. Analysis was limited to patients with diagnosis of EA and less than 1 year of age at time of surgery (neonates ≤30 days, infants 31 to 365 days). RESULTS: The study population included 255 neonates and 239 infants (at 95 centers). Among neonates, median age at operation was 7 days (interquartile range, 4 to 13 days) and the majority required preoperative ventilation (61.6%, n = 157). The most common primary operation performed among neonates was Ebstein repair (39.6%, n = 101), followed by systemic-to-pulmonary shunt (20.4%, n = 52) and tricuspid valve closure (9.4%, n = 24). Overall neonatal operative mortality was 27.4% (n = 70), with composite morbidity-mortality of 51.4% (n = 48). For infants, median age at operation was 179 days (interquartile range, 108-234 days); the most common primary operation for infants was superior cavopulmonary anastomosis (38.1%, n = 91) followed by Ebstein repair (15.5%, n = 37). Overall operative mortality for infants was 9.2% (n = 22) with composite morbidity-mortality of 20.1% (48). CONCLUSIONS: Symptomatic EA in early infancy is very high risk and a variety of operative procedures were performed. A dedicated prospective study is required to more fully understand optimal selection of treatment pathways to guide a systematic approach to operative management.
