Risk factors for morbidity and mortality in Ebstein’s anomaly: a registry-based study of 398 patients

This registry-based study of Ebstein's anomaly corroborates good surgical long-term results, while re-operation rates remain high. Patients operated before adolescence were at the highest risk of re-operation, while older age at the time of the first surgery increased the risk of CAVB. The cone reconstruction was associated with improved tricuspid valve function and a lower risk of CAVB compared to monocusp reconstructions. Choosing an optimal time window for surgery and use of the cone reconstruction may therefore further improve outcomes.
