    Abstract:
    BACKGROUND: Nonneonatal Ebstein's anomaly is a rare congenital anomaly for which numerous operative techniques have been described to repair the aberrant tricuspid valve, exclude the atrialized right ventricle, and address right heart dysfunction. We reviewed short-term outcomes in surgical patients treated by a simplified operative technique. METHODS: Our operative approach to Ebstein's anomaly is approximation of the anteroposterior commissure to the remnant septal leaflet with closure of the cul-de-sac longitudinally. Plication of the atrialized right ventricle (1 patient) and a bidirectional cavopulmonary connection (2 patients) were performed only if necessary. All patients were followed postoperatively by their cardiac surgeon and cardiologist. RESULTS: Seven patients with a mean age of 39 years (range, 3.6 to 63.8 years) underwent repair. Preoperatively all patients had 4+ tricuspid valve regurgitation and were New York Heart Association class III. Mean postoperative hospital stay was 7 +/- 2 days (range, 4 to 11 days). Mean follow-up is 42 +/- 18 months (range, 7 to 58 months). At last follow-up 5 patients are New York Heart Association class I and average tricuspid valve regurgitation is mild. CONCLUSIONS: Plication of the posterior annulus without plication of the atrialized right ventricle, resiting the tricuspid valve, or performing prophylactic cavopulmonary connection appears to be a reasonable operative approach to nonneonatal Ebstein's anomaly. Long-term follow-up of this cohort is necessary to determine the durability of such a surgical approach.
