Ebstein anomaly is a rare congenital anomaly of the tricuspid valve which presents challenges to cardiac surgeons due to the spectrum of the disease and the technical difficulty of valve repair. The natural history of the anomaly differs between patients presenting in the neonatal period to those presenting in adulthood.


A retrospective review of all patients >15 years of age with Ebstein anomaly, undergoing surgery on the tricuspid valve at 6 centers across Australia and New Zealand was performed. Patients from 1985 to 2019 were included in the study.


A total of 125 patients were included in the study, 76 patients (60%) undergoing tricuspid valve repair, of which 23 patients underwent a Cone repair and 49 (40%) had a tricuspid valve replacement. The mean follow-up was 7.9 ± 7.3 years. Postoperatively, early mortality was 3 patients (2%) and 10-year survival was 91.5%. A postoperative pacemaker was required in 24 patients (19%). Reoperation was required in 21 patients (17%). There was no statistically significant difference in survival or reoperation between patients who underwent repair or replacement of the tricuspid valve; however, with a small number of patients in long-term follow-up.


Older children and adult patients undergoing surgery for Ebstein anomaly in Australia and New Zealand experience good medium-term postoperative survival. Repair of the valve is achieved in a significant proportion of patients with increasing use and success with the Cone repair technique.
