Surgical outcome in pediatric patients with Ebstein's anomaly: A multicenter, long-term study.

Objective: Surgical outcomes of pediatric patients with Ebstein's anomaly are often described as part of all-age-inclusive series. Our objective is to focus on patients treated surgically in childhood (0-18 y). We study the intended treatment (biventricular or 1.5 ventricle repair or univentricular palliation), freedom from unplanned reoperation and survival of this specific age group, in a nationwide study.

Design: Records of all Ebstein's anomaly patients born between 1980 and 2013 were reviewed. Demographic variables, intraoperative procedures and postoperative outcomes were analyzed.

Results: Sixty-three patients underwent 109 operations. Median follow-up after diagnosis was 121 months (range 0-216 months). Twenty-nine (46%) patients required surgery in the first year of life, including 21 who required neonatal surgery. The intended treatment was biventricular (n = 37, 59%) and 1.5 ventricle (n = 5, 8%) repair or univentricular (n = 21, 33%) palliation. The one-, five-, and 10-year freedom from unplanned reoperation was 89%, 79%, and 75% respectively. There were nine (14%) in hospital deaths (within 30 d after surgery). Causes of death were low cardiac output syndrome, cardiac failure, hypoxemia, pulmonary hypertension or an unknown cause. There were no late deaths.

Conclusions: Surgery in childhood represents the worse spectrum of disease, biventricular repair is often not applied. Patients often face revision surgery. Mortality is limited to the immediate postsurgical period.
